Revert "GHOST: Fix uninitialized values."

This reverts commit aca403c819c4fc9e1e7197bbe3027d43d114bfd6.

Fix dimmed shortcut key display issues in toolbar menu and color picker.

Draw with alpha * 0.5 instead of using item them color, this doesn't work
well in the toolbar menu and highlighted menu items otherwise.

Cleanup: fix compiler warning.

Sculpt: Fix wrong object used for crazy space calculation

Was applying modifiers twice, when it should not have.

Is expected to solve mesh corruption when in sculpt mode.

Sculpt: Cleanup, spelling

Sculpt: Fix ghosting artifacts when sculpting in workbench engine

Nodes: add new image button to image nodes.

Cleanup: remove generation context from image new operator.

Fix ID buttons not working in popover menus.

Sculpt: Fix possible race condition with undo nodes

it is possible that two threads will request same undo node, only one
of them will initialize the node. The issue is that initialization is
happening outside of a lock, which was making one thread to use non-
initialized node.

If this change is ever a bottleneck, make a lock inside of node.

UI: hide empty status mouse button when dragging

Workbench: CleanUp whitespaces

Workbench: Fix texture drawing

Somehow not sure when the test for textures was performed on an
uninitialized variable resulting in never showing the textures at all

Workbench: Fix ghosting and crash in X-Ray mode

When playing animations the anti-aliasing was not reset, resulting in
ghosts from previous frames to be drawn. Also when playing animations
and switching to X-Ray mode for the first time would most likely
result in a write to uninitialized memory.

Cleanup: typos

Keymap: remove 'Screen Editing' from 2.7x map

Uses action-zones which aren't currently working in keymap presets.

addons: disable addons with versions below 2.8

Merge branch 'master' into blender2.8

Python: Print file:line when editing UI source

Cleanup: pep8
