1) Replaces the zone column with "spec"
2) Colors classes by thier class color
3) Colors level by its level difference to you
4) Adds spec to the dropdown on the who frame
5) Colors the text on the who frame like LFG (The code is almost identical)
6) You cannot sort based on the spec column. It will sort by zone or name instead.

Will display spec for other players running RockComm-1.0, so not everyone will have thier spec listed. RockComm is part of may popular addons such as Cartographer, FuBar, Pitbull, and CowTip, so there will be an existing userbase which this will work with.
