* Added a PanelType and HeaderType for registering panels
and headers in regions. When the region draws, it will
then automatically draw the ones that were registerd with
poll and draw callbacks.
Used for text header, properties and object buttons now.
* Screen level regions created for menus are now a separate
CTX_wm_menu in the context, so they don't interfere with
existing regions.
* Fix context in popup menus to always come from the area
and region the popup was opened from.
* Removed some unused context stuff: tasks and reports.
The places that were using context reports were using it
wrong anyway.
* Fix F6 closing immediately after editing a button, by
making uiBlockSetFlag not clear existing flags anymore.
* Don't use ":" in boolean X/Y/Z buttons.
WIP commit for new system to draw widgets and use themes or styles.
Not really interesting stuff to see in code now, the current
structure will change quite a lot, this to make it hook up well
to the existing system.
What works quite well is a new full opengl vector method to draw
scalable and pixel-aligned anti-aliased buttons.

* Fix for F6 redo and similar popups closing when moving
mouse outside of the popup while interacting with buttons.
* Simplify F6 redo popup code by using generated layout.
* As a test, used by:
* Object buttons, tried to make it match the mockup.
* Text window header.
* Text window properties panel.
* Panel interaction with view2d is still problematic, need to make
this work properly still.
* Templates are very basic, the ones there are simple but already
can follow the object buttons mockup quite closely.
* It's based on a three level system: panels, templates and items.
