Merge branch 'wiggly-widgets' into temp_widgets_update_tagging

Fix memory leak with loading facemap attached to bone

Fix mem leak with selected widgets, possible other mem leaks, cleanup mem freeing

Adjustments to bone face map handling

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

small cleanup in ui - removing solver res for now

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.

Slightly modified way to check for assets on loadfile.

Since we now build a list of assets and their dependencies in Library datablocks, use it!
