Fix T56659: Flow UI: Checkboxes report wrong width, making layouts jump to multi-columns too soon.

Wrong handling of ideal width when splitting buttons and labels appart
for checkboxes...

Cleanup: warning

GP: Cleanup function parameter

There was a mix of enum parameters and int/bool values.

Merge branch 'blender2.8' into greasepencil-object

Fix exception running toolbar w/o an active space

Cleanup: use single quotes for enum's

UI: remove rotate/reverse UV's from menu

These are quite obscure operations and are already available in the
"Face Data" menu.

UI: disable key shortcuts for tools

Only show shortcuts in the tooltips since they use different logic.

Cleanup: replace __import__ w/ import argument

PyAPI: add optional imports to expression eval API

Avoids having to use `__import__` to access modules.

Merge branch 'master' into blender2.8

Tool System: Show popup accelerators in tooltip

The tooltips for tools in the toolbar now show how to access.

Tool System: map keys bound directly to a tools

If a key is bound to activate a tool in the tool-system,
add this to the popup keymap.

Fix toolbar popup outside the window region

let neighbor shards now only be stopped if propagate trigger is enabled

Fix part of T56654: Freestyle hiding viewlayer buttons when there is no lineset.

Buttons' context 'path' has to bee handled carefully, especially when
building more than one step in a single call...

Keymap: Double tap A-Key to de-select all

Uses double click events for the keyboard, which wasn't used before.

Experimental feature suggested by @venomgfx

Cleanup: move select all/none/invert into template

Explicit object pointer needed for scalp access functions in RNA.

UI: correct unintended space in string formatting
