Renamed file and source folder so the Arduino IDE will open the sketch
Renamed global 'COLOUR' variable to 'LAST_COLOUR_SET' to more accurately describe purpose.
Added code to setColour() to save last colour applied. Now reveerts to last colour set when turning back on instead of default white.
Added remaining IR codes for remote. Names are subject to change, but all buttons are now accounted for.
Minor formatting and debug message tweaking
Initial work on colour increment / decrement. Already considering that a pre-calculated colour brightness array may be simpler in the long run.
