Fix negative glyph index in Team Arena text functions

Browse source 
Team Arena's text functions cast signed char values to int and use as an array index.
This works fine for values 0 to 127, but not for -128 to -1 which are a negative array index.
Instead use "character & 255" like client and original Q3 ui/cgame string drawing code.
