- Removed another key from the latch list to use as a normal key

- Required some small API changes, shouldn't affect any other Scan modules (addition of a parameter)
- Still have the latching annoyances for some of the modifiers
- Swapped Esc and Tilde for convenience
- Removed the old Esc key from the latch list (no one needs 13 latches anyways...)
- Added the control cluster mappings (Insert, Delete, Home, End, PgUp, PgDn)
- All other misc keys are currently un-assigned if a keycap legend doesn't map to anything known
  (e.g. blank keys, 000 and 00 are mapped, but your OS probably doesn't know what they mean :P)

Unfortunately, the protocol annoying, with only 3 keys having Press/Release signals.
Some of the keys were only meant to be pressed once, and do not have repeat functionality.

The current implementation is a bit slow, so some keys may get lost during USB sending.
This is probably fixable, not sure if I want to spend the time on it though.

There is a keyboard input protocol, but I'm not sure of what information can be transmitted to the keyboard.
The terminal does send some information back and forth between the keyboard, but I'm unclear of the purpose, as I can never get any response out of the keyboard.

- Better macros are still needed for the clicker
- Current macros should be separated as a sub-module
- No LEDs implement yet
- Caps Lock LED seems to be burnt out...

- Keyboard is fully functional
- LED, Beeper, and keyboard input not yet implemented

- Doesn't work yet

- Keyboard output fully working
- Not all of the features are implemented yet (input, speaker, or power
  detection)
- There is no plan for mouse support

- Full support (NKRO, provided the USB module can handle it)
- Full LED support (available to the macro modules per input signals)
- Reset/Hold line support
- Handles repeat rate issues (keyboard does not send key updates as most
  keyboards do...)
