Updated tutorial to use WildFly 8.1
Made the debugging stuff a little easier to read and remember
Fixed panel leak bug in the "remove empty docking panels" code

The bug was causing perspective switching not to work (there is a check for left-over
panels in the perspective switching routine, and it was being tripped)

There are also a few unrelated refactorings in the panel sizing code; this happened
because I forgot to commit the fix before moving on.
Fixed angular activity bootstrapping (onStartup was too early for bind())

Integration test coming soon
