replace the original one. so modifiers now work with them (apply modifier, or edit mode still work on original mesh). this should fix the three fluidsim bugs in the tracker. - fixed stupid makesdna problem (writing "char string[160+80]" isnt a good idea :) - changed GUI a bit, now displays an estimate of the required memory, there's still a problem with redrawing (currently relies on a call to the derived mesh generation) - the fluidsim struct changed to store the bounding box, and the current loaded surface mesh - temporary simulation files are now removed if env. var. BLENDER_DELETEELBEEMFILES is not set or zero - fluidsimSettingsFree now gets properly called when freeing an object
