first integration of robospice (no impact on existing project so far, just added the libraries)
[IN PROGRESS] Now that server authentication is up and running, currently configuring the POST request for authentication.
[IN PROGRESS] Switched dependencies using maven central repo instead of local jar files. Also not using services anymore, just spicing the activity. Still an error to figure out.
added gradle informations for build (to download dependencies from maven)
added bad credentials response handling (still need to display a better error message).
removed unused loading screen. Replaced by more standard ProgressBarIndeterminate view.
better failure message display.
imroved error message considering exception type.
