Shows spec icons on Unit Frames.
Sources:
0) If getting your own spec, just grabs it. This is easily accessible.
1) Checks Details to see if it has it.
2) Checks OpenRaid Library (comes bundled with Details) to see if it has it.
3) Makes a guess based on class and role (if Druid and tank, guess Guardian).
4) If all else fails, just shows a class icon instead.
Has a different icon size for raid, customizable in the Conditions tab.
