Fix silly crash on Collada

Note: This was originally wrongly committed together with an outliner tooltip
fix, re-committing separately now. See bd7060a87fd9.

Outliner tooltips: Small refactor, future proof change

In the future we may have siblings to collections (like overrides) that are not
collections. This change make sure tooltips will keep working.

re-committing separately now. See bd7060a87fd9.

Revert "Fix crash on Collada exporter"

This reverts commit bd7060a87fd9f46c2bdd141e26934e8573c6e3f8.

I mixed two commits together (a fixup for outliner tooltips and a collada fix).
Re-committing them individually.

Outliner: Tooltips for reorder operators

I really would prefer if we were to use the dropbox API for this.
That said, we now have some tooltips that work.

I'm using the new draw callback draw API for outliner tooltips.

Fix part of T53080: all material previews re-rendering after undo.

This reverts commit dc2617130b2e1d7d2b9892fbd7c6e7b60caafb66, which disabled
writing of previews for undo. While this uses some memory, re-rendering all
previews is very expensive, especially if for example you have lots of materials
using high-res image textures.

Fix navmesh creation w/ multiple objects

D2976 by @dertom

make_quickie: replace os.system w/ subprocess.call

icon update: replace os.system w/ subprocess.check_call

project_info: replace os.system w/ subprocess.check_call

Tests: replace os.system w/ subprocess.call

Saves on process creation and avoids
being tripped up by command line parsing.

Based on D2967 by @ldo with edits.

Docs: invoke_search_popup uses bl_property

Also add code example in docs.

improved rotation calculation in bind animated mesh

Outliner: Implement Add (Ctrl) when moving objects inside collection

Note there is no "text" explaining to users what is going on.
I will address this shortly in an upcoming commit.
