There were a number of issues with the model we had before, namely that plugins
that changed LED colors outside of LED modes had no way to signal "go back to
whatever color this key was". To this end, the `LEDMode.refreshAt` method is
introduced, which these plugins can call to tell the mode to update a given key.
As part of this, the API was redesigned, with code that is common between all
LED modes moving to the base class, among other things, much better names, and a
flow of control that is easier to follow.
In the new setup, there are four methods a LED mode can implement:
- `setup()` to do boot-time initialization (registering hooks, etc).
- `onActivate()` called every time the mode is activated.
- `update()` called each cycle.
- `refreshAt()` may be called by other plugins to refresh a particular key.
All of these are protected methods, to be called via `LEDControl` only.
Much of the new API design was done by @cdisselkoen, huge thanks for his work!

The new `init_mode()` method simply (re-)inits the current mode. Useful when a
plugin that changes LEDs outside of LED modes wants to reset the active LED
mode. Doubly useful when the active LED mode does all the work in its `init()`
method.

Allows setting all of the LEDs to custom, distinct colors (as opposed to
`led.setAll`, which sets them all to the same color). This allows one to
upload a theme in one go, without having to set each LED one by one.

Instead of doing a substraction and a compare in the if check, whenever we reset
the timer, add `syncDelay`, and compare against the timer only. Should result in
marginally better performing code.
Thanks @obra for the suggestion!

Because `led_sync` is a major cause of slowness, do not sync every cycle. In
most cases, it is pointless to sync 100 times a second, about 60 - or even 30 -
may be more than enough.
For this reason, introduce a timer, and a settable delay: we'll only call
`led_sync` once the delay's up. It can be set to 0 to call it every time, but
defaults to 16 (for about 62 syncs/sec), as a safe bet.
This speeds the loop up dramatically, except for the few exceptions where sync
is called.
