UI: geometry-icon alpha blend over existing colors

Useful to mix pre-defined material colors.

Fix compiler warnings.

UI/Python: layout API support for setting button emboss style.

Cleanup: deduplicate layout item initialization.

Tool System: Support set w/ space-type argument

UI: show toolbar shortcuts

When toobar text is expanded, show shortcuts
(normally confined to menus).

Tool System: tools are now set by name

This avoids having to store the tool definition in the operator
properties (on redraw).

Now just set the name, note this means we can't show the keymap in the
tool-tip anymore. This will eventually be shown in the status bar.

WM: utility to create tool keybindings

WM: Operator to set the tool by name

Needed to bind keys to tools (T55036).

Cleanup: indentation

Cleanup: add function to get class from space type

Cleanup: call toolsystem static methods directly

Note, may move these static methods into their own module.

Versioning: default scene to mean center pivot

Transform: fix regression in bound-box calculation

Error in multi-object merge.

Merge branch 'master' into blender2.8

Cleanup: trailing space

Fix 3D view axis align flag

Missed from recent pivot-point move to scene.

Cleanup: Remove unused member.

BKE_bvhutils: allow caching NULL bvh_trees.

This prevents zero-leafs bvhtrees from being recalculated multiple times.

transform_snap_object: perf: Check the distance of the bound_box of objects of type armature and curve first.

And remove unused variables.
