Area Manager: revised how an area subdivision gets managed. Originally
the 'spacedata' would store regiondata too, but this already became
impractical (like having view2d data in region is useful). So I left
that part how it is. See new diagram:

http://wiki.blender.org/index.php/BlenderDev/Blender2.5/AreaManager

This means that regions in an Area define location/size or constraints
for how they get arranged. The "RegionType" which is linked to this
defines its functionality.

For fun, test, and code validation: two temporary hotkeys added.
SKEY: splits current region horizontally
SHIFT+S: splits vertically

Note - in outliner - that "context" sticks to the Area as whole, the region
here only defines view. That's the purpose. :) For two outliners with different
context you open 2 areas.
Also note that dragging screen-edges shows the region-alignment type (split
with percentage).
