Fixed bug which caused blizzard's combat text to interpret "XP" as one of my globals. Fixed by renaming said global to XPS_XP. You should no longer get compatibility issues with blizzard's scrolling combat text.
Cleaned up the code a little - there was some XML I copied from TriviaBot which still had the markings of TB on it so I removed those markings.
Also added /xps setcol to change the UIErrorsFrame ("warning") output colour. Accepts either a name or three values - red, green then blue on a scale of 0 to 1.
