Features:
- replaces static lava models in interiors with proper Oblivion lava where possible (i.e. where all lava planes were on approximately same level)
- changes how damage from static lava is handled - instead of adding scripted fire spell it now uses Oblivion's trap system (works more precise)
- I don't know about others, but for me colliding with previous static lava models caused huge lag and black screen. It is now fixed. Also, "flowing" animation is made slower.
Merged in v054

Good job Qwerty, this was
Good job Qwerty, this was definitely needed. I never got lag with the static lava pieces, but then again, all of Morroblivion lagged for me so, I may not have noticed. :)
