Here is a patch against the 0.5.0 CVS that fixes the followin:
Drogmors available, all colors
Horse colors are now working correctly
Pretty sure I got all the drogmor/horse spells in there, if I missed some let me know.
Currently all levels of mount move the same speed (8 walking, 10 running). I need help in determining good guesses at the speed for the different levels of horses:
Slow1
Slow2
Run1
Run2
Fast
If anyone is interested in helping me with this I'll try add some # commands to adjust the speed on the fly on my server so you can play with it.
