Added British English spellings of 'color' and 'armor' to commands.

This will make things just a little easier for our friends across the pond. combat/armour now works, as well as the colour command etc.

Thank you for the submission, but the core code does not support British English spellings and this doesn't really address that (you still could not type 'help combat/armour' for instance). You can always create a personal shortcut (using the shortcuts command) if you wish to use the British spelling.
