Property Search: Sort filtered panels properly

Instead of just putting the filtered panels at the bottom, or not updating
their search order, we stop increasing the offset while the current panel
is invisible. This way the order is not completely broken if you drag to
reorder a panel while some have been filtered out.

A few bug fixes.

Merge branch 'master' into property-search-ui

UI: Slightly simplify box style panel margin offset

A small cleanup to use fewer if statements.

Merge branch 'master' into soc-2020-outliner

Header file cleanup in other files.

Fix T77204: Mantaflow Initial velocity bugged?

Always initialize the particle velocity of newly sampled particles to 0 if there are no initial velocities. Clearing the grid source makes sure that new particles will get a 0 velocity - and not interpolated from the associated grid.

Fix: Displace Modifier UV Layer UI not a pointer

The displace modifier's uv_layer property should be a pointer in the new
UI like the other modifiers use.

In some situations, the previous brush is not set. This usually happens with previous version files.

Fix T77285: Incorrect Mantaflow fluid border interaction when collision is turned off

Incorrect boolean for 'open' domain borders.

Cleanup: Don't use "Use" in boolean names

Experimental Features: Use different "categories" for different features

Right now not all the features available there have the same level of
polishing. So I split the existing options in:

* New Features [Particles Nodes]
* Prototypes [Hair]
* Debugging [Undo]
