Subject: 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!
