Create internal API method for setting the SDK's log level. Default is INFO, but if app is "debuggable", set it to VERBOSE.
Refactor tests to inherit from ApptentiveInstrumentationTestCase. Create this class, and move redundant methods into it. Set log level to VERBOSE in it as well.
For now, disable performance tests when running on an emulator.
Fix tests so the ant build properly fails when a test fails. This was keeping our continuous integration from reporting test failures. Also tweak emulator check to work more reliably.
Update README for 1.5.1 release.
