Smoke:

* cache for low res (deactivating high res for now)
* new way of view3d rendering of smoke (no longer 3 axes) -using 3dtexture now (introduced into gpu/intern)
* introducing LZO and LZMA libs into extern (makefiles missing for now)
* reducing memory usage after simulating for the frame ended (freeing temporary buffers)
* splitting smoke into 2 modifier for the cache-sake (it cannot handle more than 1 cache on the same modifier-index)
* no color on gui anymore
* fixing non-power-of-2 resolutions (hopefully)
* fixing select-deselect of domain drawing bug
* fixing drawobject.c coding style (making Ton happy) ;-)

HINT #1: If scons doesn't work -> cmakefiles are up-to-date, couldn't test scons (but i tried to mantain them, too)

CODERS HINT #1: we really need a way to disable adding all modifiers through "Add Modifiers" dropdown!

WARNING #1: before applying this commit, deactivate your SMOKE DOMAIN in your old files and save them then. You can open them then savely after that.

WARNING #2: File and cache format of smoke can be changed, this is not final!
