Master nextsteps

1. Moved tests from utils directory to tests directory
2. David had moved test_dav.py from titan to fusedav/tests; I've created test_fusedav_stress.py in the tests directory in a similar fashion
3. This file just calls "make all" to compile where necessary and run all tests in a given order
4. This test will run in whatever directory one is in when invoked; so it is necessary to cd to a binding directory before running for the results to have meaning.
