Merge branch 'master' into soc-2020-outliner

Outliner: Draw highlights as roundrects

This is an experiment to make the selection status more consistent
between the outliner, file browser, and UI lists.

Outliner: Fix bases out of sync on object drop

Outliner: Fix modifier drop index

Make modifier drop more consistent.

Outliner: Only allow object drop over name or icon

When doing object drop, allow collection drop when dropping outside the
name or icon, and parent drop when over name or icon.

Outliner: Object drop initial implementation

Allow reordering objects in the outliner. Works for multiple selection.
The code has a few places that could be cleaned up.

Also, an issue exists where it isn't always clear where to move the
objects to. This applies to any outliner drag+drop so that will be
handled separately.

Outliner: Add type options for new collections

Add options to move or link objects into the new collection from the
context menu.

Outliner: Create new collection from selected objects

Outliner: New Collection Menu

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: Disable collection reorder when sorted

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

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: Add sort by object type

When sorting by type, collections are sorted alphabetically. Objects are
sorted by their types.

Outliner: Sort collection and object names

Refactor the sorting code to apply to collections and objects, but keep
the order between objects and collections separate for now.

Outliner: Add sort method enum

Replace the SO_SKIP_SORT_ALPHA with an enum of multiple sort types. The
types are manual, alphabetical, type, and creation order. Only
alphabetical works.
