New module: geronimo-testsupport

[Jason Dillon]

I'd like to add a new module to our build, geronimo-testsupport,  
which provides at the moment a single TestSupport class which sets up  
logging and some other commonly used bits (like the File ref to $ 
{basedir}).

And then incrementally I'd like for all of our test classes to extend  
from this instead of junit.framework.TestCase.

Any objections?
