When the value returned by `millis()` overflows (after ~two months of runtime), a straight
comparison to the end time would fail. This wasn't a really big deal, but it is possible
to do it correctly, and in the process, reduce the size of the time values stored from 32
bits to 16 bits (~one minute), since the largest conceivable useful timeout is measured in
seconds (at most).
We need to prevent infinite loops, and also stop handling keyswitch events when flushing
the queue, but if we do this by setting the `INJECTED` bit in `keyswitch_state` when
calling `handleKeyswitchEvent()`, then other plugins will ignore those events, which is
not what we want; we need them to process those events as if they were real
keypresses. The solution is to use a static boolean to let us know if the queue is being
flushed.
As we guarantee backwards compatibility throughout a major version, it helps if
we have that version available, so plugins / sketches can check if they are
compatible, and issue a helpful error if they are not. As further convenience,
defining `KALEIDOSCOPE_REQUIRED_API_VERSION` before including `Kaleidoscope.h`
will result in a check being done by Kaleidoscope, and an error printed if it
does not match the API shipped.

As this is a generic plugin, for keyboards that do not have LEDs, don't tie it
to LEDControl, and don't provide a `toggleLEDs` method. Instead, show an example
how to achieve the same thing from the sketch.

At least on Linux, for a device to be considered capable of waking the host up,
it must be a boot keyboard. As we do not (yet) support a boot keyboard, we fake
one. An USB node that does nothing else than report itself as a boot keyboard,
and does the minimum amount of work to get recognised as such.
Because of this, Linux - and hopefully the other OSes too - will consider the
whole device capable of waking up the host.
This addresses keyboardio/Kaleidoscope#237, if all goes well.

Add LEDControl.paused, which we use to pause LED mode updates if true (defaults
to false). This is useful when we want to stop LED modes from updating without
switching to another (like when the host goes to sleep, and we want to turn LEDs
off).

This doesn't change behaviour at all; it's just a different way to do the computation,
which I think is much clearer. I also added an explanatory comment.
* It's now all bitwise operations, without arithemetic thrown in.
* It uses the same exact formula for finding bits on both sides of the keyboard.
* It saves 14 bytes in program memory.
Instead of hardcoding defaults for `VID`, `SKETCH_PID`, and `BOOTLOADER_PID`,
use `arduino-builder -dump-prefs` to pull these out of `boards.txt`.

When clearing a sticky, also cancel the OneShot state, and clear the pressed
bits too.
Thanks to @glasser for experimenting and coming up with the full fix.
Fixes#17.
