OSMF SVN

Adding a number of static utilities:

- setRelativeLayout, for setting relative layout parameters without having to deal with a RelativeLayoutFacet directly.
- setScaleMode, for setting scale- and alignment properties without having to deal with a LayoutAttributesFacet directly.
- setRegionTarget, for setting region target parameters without having to deal with RegionTargetFacet directly.

Example Code template for asdocs - just a few packages for now, more to be added later.

Created directory 'osmf/trunk/docs'.

Simple Regions sample, initial code commit.

Changing the Layout invalidation scheme: if one element would cause the next to be invalidated, it would take one frame for it to get updated. This caused screen flickr. Generalized the 'callLater' concept into a static utility function, that's capable of queueing up multiple functions, solving the problem at hand.

Passing the inner content layout context a reference to the region's layout context metadata, in order to keep their absolute sizes on par.

Add files to build sample applications as part of the integration and nightly build

Initial "regions" code commit.

Updating unit test to reflect changes to ILayoutRenderer.

Adding '@throws' clauses to ILayoutRenderer add/remove target methods, and adding a 'targets(target:ILayoutTarget)' method that allows checking addition/removal validity up front.
