Improved JUnit test case selections
For some reason the JUnit test case selection code
has been gone since we had the old bnd Eclipse plugin.
The old plugin could select a type/method in the 
source code, and any selected types in the package
explorer. 

I've changed the JUnit launching classes. The shortcut
now correctly evaluates the different selections
and the delegate is using this information to
instruct bnd. I also added support for the failed
test cases rerun.

Looks like few people are using this :-(
