* 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.
