First pass at fixing additional reported issues with Slann High and Life mages

Fixed an issue where the Kislev Hag cap skill had no name or description

Some beastmen skills (Ungor Beatstick and Exploit The Weak) have been adjusted due to player feedback. This is a preliminary change, and is subject to further adjustment

I am exploring options that don't directly affect battle statistics, so as to avoid unbalancing player campaigns

Added descriptions to new Hero Cap skills for DLC characters

Fixed skill row problem for Yuan Bo and Celestial General
Added hero cap skills for DLC heroes

-- Ammo skill may still be missing on new generals --

Updated for Patch

Added a unit cap increasing skill for Skink Oracles

Tzeentch lord had combat skill in the wrong row

Fixed a number of typos in skill names / descriptions. (whoops!)
