various smaller fixes / cleanup for obstacles and guiding

improved initial velocity setup for smoke and liquids

initial velocity grids now only allocated if actually enabled in UI. rudimentary support for liquid initial velocity when using plane inflow objects, proper liquid initial velocities (set invels in full volume) still todo though.

flow source UI updates

improved fluid obstacle / guide surface distance value

preserves levelset inside flow objects

cleanup in manta script exporter

added surface thickness option for effector objects (i.e. obstacle or guide objects)

obstacle grid optimization

now only allocating obstacle grids when there actually is an obstacle object present

added support for liquid guiding

guiding liquid simulations is currently considered experimental though

cleanup for smoke preconditioner (multi-grid)

better way to set preconditioner flag in dynamic scenes (scenes with moving obstacle)

added guiding parameters to UI

alpha and beta parameters are used to control lag and size of fluid guiding

updated manta pp files

various tweaks that are not in the official mantaflow branch - need to merge them there later

various fluid guiding improvements

the domain settings for fluid guiding are gone now. guiding objects handle settings individually, guiding functions kick in automatically if there is a guiding object present.

fix for levelset generation

fixes problem with multiple collision / guiding objects. levelset was overwritten incorrectly.

added options for fluid guiding

Collision settings are now effector settings. In there an object can be of type collision or guiding.

name cleanup for levelset grids

new method for levelset generation from mesh

now considering planes as well

added missing openmp files for guiding

added minimal guiding UI controls

minimal controls = toggle guiding and set tornado velocity strength

first working fluid guiding setup in smoke script

adapted spiral velocity getter from mantaflow

now possible to get 3D instead of just 2D target vel grid (useful for tornado effect)
