- clang.c includes necessary functions to make clang compiler work (tested on teensy 3.1)
- Added support code to generate a compile_commands.json for clang-tidy
  * Updates the symlink whenever cmake or make is called (Unix OSs only)

Fixes in CK3 (ghosting matrix), working version on full keyboard.

- Added fix for USB Current Change
  * If called during interrupt, could hang the I2C bus
  * Delaying I2C writes till scan loop

Added STROBE_DELAY define in matrix.h
All keys scan codes now in defaultMap.kll

- Each scan module now has a current change callback which passes the available current as a parameter
- No longer attempts to use the max 500 mA immediately, starts with 100 mA then goes to 500 mA after enumeration
- If enumeration fails due to bMaxPower of 500 mA, then attempt again at 100 mA (might also be possible to go even lower to 20 mA in certain cases)
- Now working with the Apple Ipad (no over-power messages)
- Fixed Wake-up behaviour on Apple Ipad (and likely other iOS devices)
- More effecient set_feature/clear_feature handling (device handler)
- Initial power handling via Interconnect (still needs work to get it more dynamic)

- This amount of current is guaranteed by the USB spec before enumeration
- Generally the bootloader doesn't need nearly this much, but to be safe

Added support for ghosting matrices and code for elimination.

Renamed define to GHOSTING_MATRIX.
Deleted unused files from CK3.

To use define GHOST in matrix.h, see example in Scan/CK3

Fix a handful of infinite loops that occur with more than 254 macros

Ensure directories can only be made with printable characters

 - IC60 /w Single color LEDs
 - Requires a different matrix configuration so it's incompatible with the old IC60 layout

In situations where `ls` colors directories incorrectly, the `$module`
variable contains unprintable characters. This causes directories to be
impossible to `cd` into normally, and is generally a pain.

Get build working on FreeBSD

Stop requiring editing of example scripts

The example scripts include hardcoded values that
do not work for everyone. Instead of requiring the
files to be edited (and dirtying the git tree),
allow them to take command-line arguments.

Also adds better guidance for Mac OSX virtual
serial ports.

Write whole debug cli command to history

Previously the command was being modified in place in order
to find the command name. This was happening before saving
to the history.

Fixes #70

bash might not be in /bin. Don't expect it there.

Exit quickly when cmake or make fail

The compilation process itself doesn't take very long, but it's weird to
let it continue trying to build when we've encountered an error worthy
of changing cmake/make's return codes. This gives clear indication of a
failed build as the last line of the script's output.

- Requires kll compiler update
- Includes descriptor update to handle new consumer control codes

- Works for all nodes in chain
- Synchronized to 30 ms update rate (required for ISSI chip)
  * Interconnect cannot handle full update speed from Scan module
  * Though it should be able to handle quite a bit more than 30 ms updates

- Rx buffers weren't fast enough, had to use DMA :D
- Basic LCD remote capabilities are working, single node
- Multi-node broadcast seems to have a bug still
- DMA ring buffer allowed for significant processing simplification
  * There is an overrun risk, but the buffer is large and generally there isn't too much data being sent (just very quickly)
- Split out LCD layer stack capability into itself and an "exact" version used for updating remote nodes

Fixed typo

- Now enabled by default
- Added protection around remote jumps

- 6 modes
  * Single led: decrease, increase, set
  * All leds: decrease, increase, set
- Currently update speed limited to once every 30 ms
  * Likely an I2C driver or ISSI limitation preventing even faster updates

- Implementation was completely wrong (has never worked properly)
- Now working in both NKRO and 6KRO modes
- Added more debugging code if things go wrong again

- Reverting old fix that no longer seems relevant after numerous recent USB fixes

- Also conditionally refresh the lcd screen if enabled /w interconnect
  (Not the ideal way to update, but the only way with the current KLL version)
