Fix T54544: "Copy Materials to Selected" only works when materials are defined on the mesh.

Build a temp matarray storing materials from obdata and source object
(depending on slots 'allocation' of source object), and assign those to
targets.

Also remove limitation of 'using same obdata is forbidden', just never
edit obdata materials in that case...

Certainly not perfect, but already much better than existing code.

Fix small typo in the lineart clipping calculations

Tweeks to light tree volume code

Property Search: Fixes for other-tab searching

The main change here is not running the search twice for the active tab.
We also check for the panel being active rather than just not filtered.

There are still errors when the tool tab is active, those will be solved
in a future commit.
