Fix Handle Leaks in Current Widgets
Peg 0.2.1 release.
Upping version to next release.
Updated README now that a few things are in the wiki.
Change Bubblable to a more generic name.
It won't just be for Bubble anymore, it will be for anything that we can place a PopOver shell on.
In the future, this could be a Bubble or a PopTart.
Move CustomElementDataProvider up in scope.
It's not just for notifications anymore.
Getting closer to moving Bubble common logic.
Still some reorg and documentation to do before moving forward with PopTart.
Updated docs and moved stuff around.
Fix decrepated Mock annotation.
Rename tests to match new separation of logic.
Bubble & PopOverShell are now different classes.
Only publish Sonatype SNAPSHOTS from RT repo.
Initial PopTart implementation.
I'm going to make a more sophisticated example next.
Moving logic around between Bubble & PopOverShell.
Stopped up the leak introduced with the refactor.
This is cleaner, anyway. We shouldn't have subclasses dealing with the details of attaching a listener.
