Adding ability to specify -installedApp on command line.

Allows one to run tests locally without having the standalone server install an app every time.
deactivate test
some responses don't return a value all the time (like execute script without 'return')
changing the interface to pass the AndroidApp instead of a string to the apk file.

adding some printstacktraces to attempt to troubleshoot errors that happen on the server
(it's not nice to swallow errors anyways)
use project version of dependencies (avoid maintenance and the mishap of missing one)
Logging output from any executed process
