Fix Smoke:
*totally forgot scons file for lzma

Fix Smoke #1:
* compile error reported by nudelZ (static/nonstatic)

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!

* volume rendering cleanups and optimisations

* CMake fixes, mustn't have come through in the merge

2.5/Paint:

* Some initial work on a new paint abstraction, PaintStroke. For now, most of the code just pulls out stroke-related stuff from sculpt mode, next step is to integrate the other paint modes to use this. It'll enable stuff like smooth stroke for all the paint modes with less code duplication.

2.5/Multires:

* Fixed saving most recent sculpting on a multires object. Uses the same hack already in place for saving that info for undo.

More texnode preview fixes. Previews now have correct aspect ratio and are drawn by the renderer.

texture enum was crashing when generating docs, removed radiosity from makefiles.

2.5: Restored statistics in the info header.

Implementation:
* NC_SCENE or NC_OBJECT cause scene->stats to be cleared.
* NC_INFO is sent to tag info headers for redraw.
* In UI scene.statistics() creates scene->stats if it is
NULLd, and then returns the string.

- fix for BGE warnings
- when C++ uses guardedalloc SYS_DeleteSystem was called after MEM_printmemlist(), making it look like there was a leak.
