Merge pull request #16 from Sebsebeleb/master

Domains!
Added requirement to blood vengance
in-game help (no actual key bound)
Improved the feat dialogue to update automatically!
Merge branch 'master' of https://github.com/Zireael07/Underdark
Fixed new hotkeys (h to show help, b to show spellbook if you have) however, you have to enter the key binding dialog in the options once before the keys are actually bound
