Rewrite MouseKeys plugin

Browse Source 
This is a major rewrite of the MouseKeys plugin, primarily focused on mouse
cursor movement keys.  There is no change to the keys themselves, and the
behaviour is fairly similar, but there are now better configuration parameters
and defaults.  The new parameters are a minimum speed, a maximum speed, and the
length of time it takes to reach that maximum speed, without needing to worry
about the report update interval.

The plugin provides a number of keys one can put on the keymap, that allow
control of the mouse. They can be divided into a few groups:
### Cursor movement
### Mouse buttons
Mouse button keys are straightforward; pressing one is the same as pressing the
corresponding button on a physical mouse. You can hold a mouse button key to
perform drag gestures, as you might expect. MouseKeys supports five mouse
buttons: left, right, middle, previous, and next.
* `Key_mouseBtnL`, `Key_mouseBtnM`, `Key_mouseBtnR`, `Key_mouseBtnP`,
`Key_mouseBtnN`: The left, middle, right, previous, and next mouse buttons,
respectively.
The simplest set of keys are the mouse cursor movement keys. These move the
cursor one direction or the other, with speed and acceleration factored in. When
a mouse cursor movement key is held down, it will move `.speed` pixels each
`.speedDelay` milliseconds without acceleration. But when `.accelSpeed` is
non-zero (and it is not zero by default,
see [below](#accelspeed-and-acceldelay)), the speed will increase by
`.accelSpeed` every `.accelDelay` milliseconds. Thus, unless configured
otherwise, holding a direction will move that way at increasing speed.
### Cursor movement
One can hold more than one key down at the same time, and the cursor will move
towards a direction that is the combination of the keys held. For example,
holding the "mouse up" and "mouse right" keys together will move the cursor
diagonally up and right.
When a cursor movement key is pressed, the mouse cursor will begin to move
slowly, then accelerate to full speed. Both the full speed and the time it
takes to reach full speed are configurable.
The cursor movement keys are as follows:
@ -60,26 +62,18 @@ The cursor movement keys are as follows:
* `Key_mouseUpL`, `Key_mouseUpR`, `Key_mouseDnL`, `Key_mouseDnR`: Move the
cursor up-left, up-right, down-left, down-right, respectively.
### Scroll wheel
### Scroll wheels
Controlling the scroll wheel is similarly simple. It does not have acceleration,
but one can control the speed with the `.wheelSpeed` and `.wheelDelay`
properties (see below).
Controlling the scroll wheel is similarly simple. It does not have
acceleration, but one can control the speed with the
`MouseKeys.setScrollInterval()` function, which controls the length of time
between scroll events.
* `Key_mouseScrollUp`, `Key_mouseScrollDn`: Scroll the mouse wheel up or down,
respectively.
* `Key_mouseScrollL`, `Key_mouseScrollR`: Scroll the mouse wheel left or right,
respectively.
### Buttons
Buttons are even simpler than movement: there is no movement speed, nor
acceleration involved. One just presses them.
* `Key_mouseBtnL`, `Key_mouseBtnM`, `Key_mouseBtnR`, `Key_mouseBtnP`,
`Key_mouseBtnN`: The left, middle, right, previous, and next mouse buttons,
respectively.
## Warping
Warping is one of the most interesting features of the plugin, and is a feature
@ -210,37 +204,32 @@ the following additions:
The plugin provides a `MouseKeys` object, with the following methods and
properties available:
### `.speed` and `.speedDelay`
### `.setCursorInitSpeed(speed)`/`.getCursorInitSpeed()`
> These two control the speed of the mouse cursor, when a movement key is held.
> The former, `.speed`, controls the amount of pixels the cursor moves, when it
> has to move, and defaults to 1. The latter, `.speedDelay` is the amount of
> time - in milliseconds - to wait between two movements, and defaults to 0, no
> delay.
> Controls (or returns) the current starting speed value for mouse cursor
> movement. When a mouse movement key is pressed, the cursor starts moving at
> this speed, then accelerates. The number is abstract, but linear, with higher
> numbers representing faster speeds. Default starting speed is `1`.
### `.accelSpeed` and `.accelDelay`
### `.setCursorBaseSpeed(speed)`/`.getCursorBaseSpeed()`
> These two properties control the speed of acceleration. The former,
> `.accelSpeed`, controls how much the speed shall be increased at each step,
> while the second, `.accelDelay`, controls how often (in milliseconds)
> acceleration should be applied.
>
> They default to 1 pixel and 50 milliseconds, respectively.
> Controls (or returns) the current top speed value for mouse cursor movement.
> When a mouse movement key is pressed, the cursor accelerates until it reaches
> this speed. The number is abstract, but linear, with higher numbers
> representing faster speeds. Default full-speed value is `50`.
### `.wheelSpeed` and `.wheelDelay`
### `.setCursorAccelDuration(duration)`/`.getCursorAccelDuration()`
> The last two properties supported by the plugin control the mouse wheel
> scrolling speed. The former, `.wheelSpeed`, controls the amount of ticks the
> wheel shall scroll, and defaults to 1. The second, `.wheelDelay`, controls the
> delay between two scroll events, and defaults to 50 milliseconds.
> Controls (or returns) the current time it takes for the mouse cursor to reach
> full speed (in milliseconds), starting from when the first movement key is
> pressed. Default value is `800` ms.
### `.setSpeedLimit`
### `.setScrollInterval(interval)`/`.getScrollInterval()`
> This method sets the maximum speed after which acceleration stops.
> The default is 127, and the minimum value is 16 (things will not work
> properly below 16).
> Controls (or returns) the current scrolling speed, by setting the time between
> mouse scroll reports (in milliseconds). Default value is `50` ms.
### `.setWarpGridSize`
### `.setWarpGridSize(size)`
> This method changes the size of the grid used for [warping](#warping). The
> following are valid sizes: `MOUSE_WARP_GRID_2X2`, `MOUSE_WARP_GRID_3X3`
