Add all the spaces :)

Use the arrow keys to navigate between the last N commands, similar to
most shells.

Sometimes it would be nice to clear the screen if it has a lot of
information (ex: when in debug information). Some terminals support ^L
to clear screen, but not all (iTerm2 on my mac does not), so I think
this is worthwhile to add.

Edit: Forgot cli.h

* Keyboard interconnect using two uarts
* Supports daisy chain addressing using a master/slave direction communication scheme

- Still needs more testing
- Functions have been tested alone to be generally working

- Added AddModule CMake function which simplifies specifying module requirements

- It's possible to get even more, but this is probably as far as I'll go
- PROGMEM is really annoying to use, and makes the code look like ass
- Now the Teensy 2++ should have enough RAM to use PartialMap easily

- Changed static variables to const that should have been const
- Updated CMake files to prepare for MCHCK custom bootloader
- Changed the USB ID numbers and ID number for bootloader
- Only generate DFU or Teensy binary image, not both
- Fixed RAM and FLASH calculator
- Added missing license in delay.c/h (much of it was taken from Teensy source though I've changed a bunch of it)
- Prepared mk20dx.c for upcoming bootloader addition
- mk20dx.h cleanup
- Reduced the MCHCK based flash size for the application image (bootloader changes requires more flash space)
- Fixed bugs in macro.c
- Added keyHold cli command
- Added show pending events debug message for PartialMap macro module

- Initial work on capSelect command
- Toggling for macroDebug (only basic functionality right now)
- Cleanup

- Code should be working, but much is untested
- All of the old modules will need to update and use the new DefaultMap keymap
- There might still be some naming conflicts with some Scan Modules

- Includes serial putchar and getchar cleanup (overall)
- Moved avr-capsense to DPH (renaming)
- Basic cleanup for including CLI on the avr architecture

- Fixed no argument default (would skip the null in some cli commands)
- Added free running force/distance measure
- Most of the help information
- Zeroing force and distance
- Start/End marker setting

- Hex debug for debugging VT100 control characters from the keyboard
- Renamed reset to restart (software reset)
- Added reset command (same as bash reset, which resets the VT100 variables)
- Cleaned up the version module field

- reset   -> Simulates power cycle (Not yet compatible with AVR)
- reload  -> Sets the device into firmware reload mode
- led     -> Toggles the error LED
- version -> Displays detailed version information (additions to CMake files was necessary, might have broken Windows builds...)

- Issue with the first space delimiter before the args

- Supports multiple custom command dictionaries
- Basic handling of control characters
- Initial dictionary for integrated commands

* Initial cli code
