Instead of manually counting set bits, use gcc's `__builtin_popcount()` for a -
supposedly - more efficient count.
Also initialize the counter to zero, while there.
Fixes#11.

Instead of `getKeyswitchStateAtPosition`, which is long, unintuitive and feels
wrong too, introduce `isKeyswitchPressed`, shorter, better, more
reasonable (because it returns a bool - we support only two states anyway!).
Additionally, add `pressedKeyswitchCount()`, which returns the number of key
switches pressed.

Instead of running `scanMatrix` whenever we get there, use Timer1 to set a
consistent period. This does not mean we'll run every time the timer is up, but
we will run at consistent intervals.
Fixes#6.

As this is a new port, there is little sense in supporting the legacy API.
Disable it for some nice space savings!

This adds a very simple debouncing algorithm for debouncing. It works by making
sure a key is not changing state more than a configurable amount of cycles.
Defaults to five cycles for now.

The global `ErgoDox` symbol should be a shortcut, an alias, to KeyboardHardware.
When using ErgoDox-specific functionality, `ErgoDox.someMethod()` is much
clearer about that than `KeyboardHardware.someMethod()` would be.
