Added automatic line separation and Keylistener for posting 

Improvements yet to be made (help wanted!):
* automatic line separation does not work
* automatic line separation needs a case for insertion of a String
* Keylistener for Posting does not work
* Method for listening to multiple keys needed (ctrl+enter)
* A template Settings screen was added, has yet to be polished
