Merge branch 'undeads' into 'master'

Undeads

Alters a variety of Undead enemies and the Blighted Ruins enemies.
Should reduce the frequency of level < 5 characters being squished by a standard undead, by adding in a couple extra critters and bumping the levels up on the rest. This will make the Ruins of Kor'Pul and the Blighted Ruins a little easier.
The Bone Giant base has had its dex reduced by 30, but its movement speed increased by 50%. This is done to stop the Half Finished Bone Giant having 40ish dex which made it rather annoying if it rolls a shield rune. It doesn't get the movement speed bonus though.
Vampire and Wight minimum levels were also altered. They had a tendency to introduce themselves to the player on the same dungeon floor, rather than in a tiered progression. Wight talents were also tweaked so they aren't all the same.
All the Skeletons have been given descriptions by Hogulus.
Added an elite Skeleton Ninja for FUN.

Could do with some focus group testing and a few new tiles for the skeletons.
