Merge branch 'master' of git.scc.kit.edu:xt9634/ProofScriptParser

* 'master' of git.scc.kit.edu:xt9634/ProofScriptParser:
  New Script Tabs loadable and concept for loading a file again is implementend: if file is already laoded and loaded again, it is overwritten (Decision for the beginning); part for right side is coming in the next days ;-)
  New Tabs loadable and concept for loading a file again is implementend: if file is already laoded and loaded again, it is overwritten (Decision for the beginning)
  small improvements
  Better StatusBar, little refactoring in contract chooser
  Empty tab pane has buttons now, need to add the appropriate Action
  Empty TabPane (not final yet)
  Fixed issue back
  Initial Tab for scriptArea
  Added tabbedpane in fxml for scriptarea and model skelett for inspectionviewmodel
  CodeArea's syntax highlightning
  added first part of parser testcases
