* Updated rules.mk
* Mapping for layout was flipped
* Figured out how to re-map bad pins.
* Updated Keymap

* Added QMK_KEYS_PER_SCAN
* Removed more unnecessary files, since split_keyboards are in main QMK branch already.
* Simplified rules.mk in rev1
* Removed i2c from matrix.c
* Re-formatted to 4 spaces per tab,
* Changed note for NUMPAD
* Added I2C support back!
* Fixed keyboard mappings. Both sides work
* Moved i2c configuration from keymaps/default/config.h to config.h
* Changed SCL_CLOCK to 400000L
* Added DEBUG_MATRIX_SCAN_RATE for future optimization efforts
* Removed row2col code to clean up matrix.c
* Scan rate from 2100 -> 4200 by using Nop instead of waiting 30us between columns.
* Further optimized column reading via optimized_col_reader.
* Immediate key-recognition
* Switched back to own implementation of SPLIT_KEYBOARD. Will optimize so that slave interrupts master.
* Moved scanrate debug messages to another file.
* Made matrix_scanrate.c compile if CONSOLE_ENABLE is off. Updated to latest i2c.c
* Latest i2c uses a few bytes for lighting information
* Optimizations in i2c.h to determine buffer size.
* Disabled a whole bunch of features. TODO: Test that keyboard still works fine.
* Minimum #define NO_ACTION's with still working keyboard
* Fixed matrix not working due to offsets not being respected

* Added audio on and off for numlock.
* Renamed from xeal60 to xealous, simplified build system.
* Used more shared split_common code.
* Updated audio code.
* moved tone_qwerty and tone_numpad to config.h. Removed keymaps/default/config.h
* Added more shortcut keys in _FN layer. Increased debounce to 6ms due to fencepost error.
