#29 Alt support - Roster changes

[Craig Vincent]

Need to add alt distinction in the guild roster. Probably
just easiest to color code (similar to how red names
currently are admin, blue are normal members). Maybe
make alt characters (known by the 'main' column in
eq_guildmembers = 0) green. The color scheme could
also be config oriented.

This update needs to affect both admin and player based
rosters
