Outliner: Activate collections with selection

Restore original behavior.

Outliner: Move collection colors from submenu

The goal is to draw them on a single line, perhaps a template is needed
here.

Outliner: Remove need to hold shift when parenting

https://developer.blender.org/D3812 discussed reasons why holding shift
to parent was needed. Now in the outliner we show child-parent
relationships clearly in View Layer mode so this extra modifer key is
not needed.

When dropping over an object name the parent operator is used, and when
dropping anywhere outside the object name will move to collection.

Outliner: Disable collection reorder when sorted

Disable reordering collections in the outliner when not in manual sort
mode.

Merge branch 'master' into soc-2020-outliner

Add custom tag support to assets

Tags are basically a list of strings. We could optimize these in future if
needed. We could also easily add colors or icons for individual tags (e.g. like
on developer.blender.org).

Note that there's no UI for this yet. Functionality is available via Python
though.

Property Search: Fix panels occasionally overlapping

Remove uses G.debug guards from CLOG (simple cases)

Support arbitrary descriptions for assets

Simply have a dynamic string in the asset data-block. That can be set and
updated at any point.

Property Search: Fix panels animating when added

Merge branch 'master' into property-search-ui

Experimental: remove debug arguments from function, remove debug guardsfrom logs

This is to see if loggers should be influenced by code.
Also rename function to *_sprintf

Support preview thumbnails for new asset data-blocks in file browser

Assets have to own a copy of the referenced data-block's preview for this to
work. We *could* do without that, but it complicates partial reading of
data-blocks for the file browser (which may be addressed with further work
though).

Volume: Added slicing options in 'Viewport Display' for Volume Object

Merge branch 'master' into soc-2020-info-editor

Command line arguments: separate log level into severity and verbosity

Workaround: logging big messages causes crash

Rename clog check macro

Tweak log levels

Use new Asset data-block type for "Create Asset" operator

AssetData is unused now. Just keeping it in case it's useful later (to avoid
having to do the monkey work to add it again).
