Moving PasteDeploy's tests to compat directory
Adding a looponfail convenience environment to tox. (TDD yay.)

Slightly less crude implementation of interface.
compat/test_[config|filter].py should work with the testapp fixture also

Previously they worked when all tests were run in the session because previous tests used the fixture and would set up the module. This turned out to break when they were run individually.
Basic usage of the compat.loadapp function now goes through the real Montague interface!

Stuff involving manipulation of the defaults with the 'get' and 'set' prefixes are unsupported, as are filters.
