Blender Git Loki

transferred object velocities to mantaflow

removed some deprecated functions

simplified grid pointer access functions

Merge branch 'master' into fluid-mantaflow

removed deprecated cmake setup

removed old manta_pp files from internal python dir - manta_pp files are in intern/mantaflow

minor formatting cleanup

better use smaller uvweight reset time (strange smoke movement when set too high)

reverting to original fluid solver destructor. additional guards not needed.

making sure that all python objects are garbage collected

first customizations for using mantafow flags grid (replaces obstacle grid / array in blender)

important: initialize uv helper grids as well

added caching for mantaflow texture grids

better and safer to delete solver python variables (and thus trigger object deletion) at the end

added current frame number to manta step. useful for standalone mantaflow script usage and for correct caching (uvweight)

run uv setup strings only when using high res

switched back to old uv setup using low res solver

generalized mantaflow grid helper functions

implemented external forces

crash fixes when loading a new script and some better default parameters
