Added v1.0 release + major refactoring and changes, read comment

- Added persistent data via shared prefs, also the favorites work now like that, database wasn't working till now, which was the reason for that addition
- Switched all JSON handling to GSON library as it is much more performant and easier to use
- Refactored Classnames to be more consistent
- Finally made the Webservice Async, switched all requests to the new service

I still need your sha-1 fingerprints for the map api to work in your compiled apps...enter this in terminal/cmd

```
keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android 
```
and send me the sha-1 fingerprint via email, so I can add it in the api console...
