Adjustments to bone face map handling

Making it work for copying bones, proxies, correct id user handling, etc.

More refactoring of the update->draw routine

We never recreate widgets anymore, we only create them once using an init callback and handle changing data in update callbacks.

For efficiency, we now have 3 widgetgroup init/update callbacks:
* init - initialize data that doesn't change in widget lifetime
* refresh - update data that doesn't change each redraw, only called if WM_widgetmap_tag_refresh was called before
* draw_prepare - update drawing data, called before each redraw

This should really increase widget drawing performance.

Note: Widgets other than the transform manipulator are still not adjusted to work in new drawing routine.

Initial implementation of a tagging system for widget updates

Instead of recreating all widgets on (almost) every redraw, we just recreate them now if WM_widgetmap_tag_recreate was called before.
Since some widgets still have some data that needs to be updated before drawing, an update callback was added to widget groups for doing this.

Note: This branch a bit unstable now, basically all manipulators except of the transform manipulator are broken now.

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.
