fix for alembic mesh exporter

liquids and smoke can both be of domain type. checking for smoke domain needed to be more specific, i.e. now checking domain type as well.

re-enabled bubble rise factor and some small snd particles fixes

fix for particle and mesh scaling

obvel velocity fix, disabling surface tension and viscosity for now, set do not delete flip in obstacle

updates for new manta pp files, also added first setup for viscosity and surface tension

added missing ray normalization in levelset generation call

updated manta pp files

openvdb changes for manta support

customization for obstacle grid to match mantaflow flags grid

changes for quick smoke cycles node setup and minor bug fixes

with quick smoke, the cycles setup for fire was unreachable (why?) -> removed the if-clause. also fixed minor bugs (UI Quick Liquid, copy settings for effector object)

Merge branch 'master' into fluid-mantaflow

fix for particle count in UI

was missing count reset

disabling fractions and enabling moving obstacles again

fractions do not support moving obstacles right now. also, fractions combined with obstacles results in particle leak (likely because of inaccuracies at fluid/obs border when repeatedly subtracting from phi grid - sdf not preserved)

big fluid particles update

- refactored original snd particle functions on mantaflow side
- bug fixes for particle reading (fixes disappearing issue when using
various ptypes at once)
- added support (esp. in caching) for future particle life vector (on
mantaflow it's side already in use. todo: copy values to blender
particle systems)
- memory optimization: only allocate particle fields when they're
actually enabled in UI
- fixed standalone script export (snd particle system, pdata fields)

fluid particles UI update

cleanup for adaptive time stepping

especially the timestep was too big and resulted in adaptive steps when adaptive stepping was actually disabled.

general cleanup

fix for initial velocities

added sanity check that clears any left over velocities

fix for liquid velocity bug

now explicitly setting initial velocity in inflow region. this solves the problem where liquid inflow becomes unstable over time. it also allows you to use liquid plane objects with initial velocity (similar to smoke). for proper liquid initial velocities a volume initialization is needed though (todo).
