Instead of having a previousState and a currentState, of which at most
two bits are used, use a single byte. This saves us a lot of code space,
and makes a number of things easier, too.
The helpers were redone as macros, since they are just bit checks now.

They are not used anywhere, and as such, are a distraction. The states
will be reworked into something similar that was now dropped, but that's
a separate patch.

The INJECTED flag can be used by handlers to determine where the event
originated from: as a result of a direct keypress, or if it was injected
into the event loop some other way.

Moved the library sources into src/, and the sketch into examples/. This
makes it easier to use the project as a library, and the default
firmware sketch shows up in Arduino IDE's Files/Examples menu. This in
turn, has a very neat side effect: an end user can start from this
example, and when they save it, it will be saved to their Sketchbook,
and the library can be updated independently, without having to worry
about conflicts.
Having the Sketch separate from the sources also paves the way for
moving the keymap there.
As far as Arduino IDE dependencies go: this requires Arduino IDE 1.6.7+,
the same minimum version required previously.
