Fixed regression in ParentChild caused by Widget nested UIEvent fixes. Fixes #2530400

Fixed UI_EVENTS invoking nested Widget listeners more that once. Added UIEvents test cases (that Ryan Grove is a bad influence). Fixes #2529723

Temp patch, until i figure out multi instance issue. See #2529724

Fixed multiple delegate listeners attached to the same node, for UI_EVENTS support. Regression introduced when we moved the map of delegate listeners from a global/static to an instance based property. Fixes #2529634

UI Events Fix: Needed to split on event prefix delimiter, after going through parseType, in order to support on('foo:click') etc. Fixes #2529562

APIDocs: Added new submodule docs. No -min files were hurt in the making of this commit point

Fixed after handling for UI_EVENTS when using the object literal signature. We now only override on, and go through EventTarget's parser. Fixes #2529530

Attach delegate listener for UI EVENTS to boundingBox as opposed to boundingBox parentNode (which was done originally to workaround delegate issue - where delegate didn't include the container node in it's filter matching). Fixes #2529326

Widget kweight optimization. UI_EVENTS and getSkinName functionality broken out of widget-base. No impact if you're using "widget". If you're using "widget-base" explicitly in your meta-data/use statement, you'll need to include "widget-uievents" or "widget-skin" if you need the broken out functionality. "widget-base-ie" has also been broken out. Still need to add conditional loading meta-data, but it's still included in "widget"
