Factorize gridflow computation code.

Fix gridflow layout logic, and building with bplayer.

Also add the 'modulo' option for columns number (i.e. set number
automatically, but only allow multiples of given number).

Notes: changes to properties_data_mesh.py are just for testing
obviously, will be reverted for final patch!

Add gridflow layout RNA API

Initial (and theorical) code for grid flow layout.

Needs RNA API, and... testing! :P

Move active screen layout into the active workspace

Changing the workspace now also changes the layout. Note that there is a drawing issue here so you'll have to move the window to see the change. There is also a crash when closing Blender, need to investigate some more.
This commit also cares for compatibility, we simply create a new workspace for each screen layout of the old file.

I want to avoid any low-level access of workspace related data, instead everything should go through an API. Thus I also added some API functions for workspaces.
To store bScreens (aka layout) using a ListBase in a workspace, I had to add a bScreen wrapper, called WorkSpaceLayout.

RNA: layer.objects.selected

Instead of exposing the base I think this may be nicer for the API. We still need a way to change select for a layer though (expose the ObjectBase perhaps? :/)

layer.engine

layer.objects.active

layer.active_collection

This one is straight from the "layers" branch. I nailed it quite nicely there, so it was simply a matter of bringing it over :)

Shuffle code around to re-order functions

layer.objects

DNA documentation

BKE_collection_remove: (also first of five of the syncing functions)

Cycles: Clamp optimal bandwidth parameter to the range of evaluated parameters

moved forces to pre step function and now resetting inflow obstacle with 0.0 (instead of 0.5)

RNA layer collections

Fixup for new layers

Merge remote-tracking branch 'origin/master' into soc-2016-cycles_denoising

Cycles: Actually enable FTZ

The previous commit added the function to enable it, but didn't ever call it...

Rename CollectionBase > LayerCollection
