Cycles: missing break in GridDescription loop.

Correct update in RNA and send notifier.

Cycles: remove grid name print.

Cycles: tag OpenVDBManager as needing an update when connecting node
sockets during preview rendering.

Cycles: early exit add_volume if we already have a sampler allocated.

This is done by means of a vector of structs which stores the grids'
information, including the grid slot, which is returned if we have a
match.

Fix crash happening when exporting the simulation right after resetting
it (by enabling adaptive domain, high resolution or whatever).

The fluid description should be set after the simulation was
initialiazed as it contains information taken from fields which wouldn't
exist otherwise.

Fix compile issue.

Add an operator to update the transformation matrices of the grids.

Cleanup: grid naming, use CFRA, quiet warning, unused include.

Fluid transform cleanup (avoid reinventing the wheel).

Cycles: add some quick logging.

Fix missing object drawing update when done exporting.

Fix fluid transformation matrix.

There's a little bit of float precision issue, but I'll call it a day
for now...

Merge branch 'master' into openvdb_smoke

Dynamically add sockets to the node based on the grids available in the
file.

Move openvdb utilities into their own files/directory.

Cycles: only store a single float for scalar outputs.

Cycles OpenVDB node: add output sockets based on Blender's node outputs.

In a later commit, the Blender ones will be dynamically added based on
the grids contained in the file so any grid can be accessible for
shading purposes.

Apply patch in a new branch, to clean the history a bit
