Add debug messages
Add newline for work_queue output
Add data files with test module install
Adjust test loading to be more flexible

Previously, tests would be loaded from a "test" folder
in the current working directory. This would fail if
trying to run from the installed forcebalance.test location.
Now the __file__ variable is used to determine where tests
are being run from and the test directory is set appropriately.
