[modules-dev] Review request for 6608500

[Dave Bristor]

Hi folks,

This cleans up some tests.  It includes the changes we mentioned yesterday 
w.r.t. *Repository implementations: they can now be configured from system 
properties, and those values override values in the Map<String, String> that's 
provided when the instance is created.  These changes should keep old test 
files from filling JPRT's temp directories.

Please note that, with respect to configuring repositories use of the Map is 
still in LocalRepositoryTest and URLRepositoryTest.  Testing via 
System.getProperty is in BasicLauncherTests.

Thanks,
	Dave
