adding ability to test ios-driver mobile safari with the python tests.

running the tests -
./go //py:mobileSafari_test:run
./go //py:mobileSafari_iPad_test:run

re-running a failed test (after you run and don't run 'go clean'):
build/python/bin/py.test build/lib/selenium/test/selenium/webdriver/mobileSafari/<test_file>_tests.py -k <test_method_name>
need to switch back to default frame to get this result
type first letter in caps so it works on mobile with auto-cap too
mobile safari doesn't allow named windows
can't change window position or size in safari
fix this test to use the actual title of the switched-to frame
removing the javas
fixing more javas
