Merge branch 'miscareagen' into 'master'

Misc Zone Generation Changes (1.7beta6)

Significant changes:  

* Add uniques to rak'shor pride, similar to the ones already showing in all other prides. Uniques are randomly chosen between necromancers or corruptors with either a necromatic mass or sanguine horror pet.  
* Reduce the size of eruan floors (but maintain total number of NPCs). Reduce eruan from 4 floors to 3.  
* Buff various talents nerfed incidentally in prior 1.7 changes. This is not buffing them in comparison to their power in 1.6, but rather returning them to 1.6 levels of strength.  
* Fix ruined dungeon rares spawned by orbs dropping items.
