Update gametime.lua

Hi! First of all thanks for creating this addon.

I did some small changes to help customize the addon interface a bit more


//gt daySize 10 = Changes day font size to 10 dpi
//gt dayFont Verdana = Changes day font face to verdana type
//gt timeSize 10 = Changes time font size to 10 dpi
//gt timeFont Verdana = Changes time font face to verdana type


Also I did include an extra mode for a more compact display. For example the days are displayed using the degree symbol '°'.

Please let me know if you see any problems with this code.
