#62 Colour/Color bug

[ui_486]

mIRC colours option eats too many characters, consider:

@12100.00

Where the @ is the colour code character. jmIRC will show as ".00" or something like this, when it ought to show "100.00" in a darkish blue.

IMO It should only accept the following colour code strings:

@00, @01 ... @09, @0, @1 ... @9, @10, @11 ... @15

and likewise with background colours
