**UNTESTED**
- The file calling OTestQuery now looks for the correct framework depending on the WRAPPER_EXTENSION setting.
(This setting defaults to SenTestingKit if the key doesn't exist or if the value is empty.)
- The OTestQuery executable now takes two arguments: the bundle path, and the name of the framework class.
(Currently either XCTestCase or SenTestCase.)
- OTestShim blindly attempts to shim for both SenTestingKit and XCTest.
- Unit tests were updated to conform to the updated method signatures.
