Manipulator: name remove func's 'unlink_delayed'

Name wasn't right since this only unlinks from manipulator maps.

Manipulator: move 'Scale Cage' to its own tool

Was activated with the regular scale manipulator,
move to own tool since they are different ways to access scale.

Fix merge error

In a previous merge, this file was wrong.

WM: Initial Tool System

The tool-system it's self is primitive and may be changed.

Adding to 2.8 to develop operators and manipulators as tools.

Currently this is exposed in the toolbar, collapsed by default.
Work-flow remains unchanged if you don't change the active tool.

Placing the 3D cursor is now a Click instead of a Press event,
this allows tweak events to be mapped to tools such as border select,
keeping click for 3D cursor placement when selection tools are set.

Merge branch 'master' into blender2.8

Cleanup: use relative imports in bl_ui

Silence warning on subsurf modifier

Cleanup: Remove unused code

Pass bmain explicitly rather than via bContext

Passing main makes function easier for re-use.

Cleanup style

Cleanup style and variable names

Cleanup: Replace duplicated poll lines by function

Rename texture_shift to texture_offset

Depsgraph: Reduce number of depsgraph_legacy usages outside of depsgraph

Depsgraph: Make depsgraph a part of evaluation context

This way evaluation routines will know which exact depsgraph evaluation
is happening for.

Mainly needed to get evaluation flags associated with ID nodes.

Fix/workaround wrong dependency graph being constructed after creating a proxy

Factorize repo editing 'write on disk' code, and add relevant update callbacks to repo's RNA properties.

Also made writing repo DB on disk slightly safer (using atomic file
swapping instead of directly writing into real repo DB file).
