Cleanup: Move functions to proper place; naming

Minor refactoring to widgets user preference options

Some edits to namings, descriptions in code & UI. Manipulator size of older .blends is now overwritten, don't think it's worth doing version patching.

Fix glitchy manipulator when overlapping with facemap widget

Correct trackball widget name

Draw selected widgets before others

We want the manipulator to be in front of facemap widgets.

Fix widget scale option not having influence with '3D Widgets' enabled

Transform Manipulator: Draw planar widgets while tweaking (with ghost widget)

Transform Manipulator: Increase line width of dial widgets

Gives a bit better contrast to grid floor. It looks a bit clumsy now, but this might just be a matter of getting used to it.

UV Editing Transform Manipulator (WIP)

This commit adds an initial (but definitely usable) transform manipulator for UV editing in the UV/Image Editor. Only translate is supported for now.

Remaining ToDo's:
* Intersection test is not working completely yet - only arrow line is used (which for some reason isn't working completely either)
* Add rotate and scale manipulator
* Add screen space translation widget (would be unconstrained actually)
* Add toggles to enable/disable and changing transformation type
* Some of the math added for intersection tests could become BLI_math functions

Some tweaks to new low-level widget utility API

Correct comment (and add another one)

Only show widget select keymap items for widget groups with selectable widgets
