Combat Log 2

It's now possible to set the colour of text output to the combat log;
passing the GUIManager an array strings and an array of colours, each
string is output with the corresponding colour, on the same line.

CharacterComps now have a colour associated with them, used to colour
their name when it's output to the combat log. Colours are represented
by the struct "col", defined in GUIManager.h, which holds int values (0
- 255) for R, G and B.
