Red/Orange/Purple Gems Missing from Item Picker for Casters

[sanguinerarogue]

Spell damage gems not showing in picker (red/orange/purple). Appears to be working for melee classes.

Possibly is due to needing to update the Weighted/Displayed stats for the casters. Going from MoP back to TBC meant ripping out Spell Power and adding back Spell Damage (and independent School Damage), but these specs might still be looking for SP.
