Added ls_rest_adapter.js containing our own emberdata adapter implementation to store data in local storage and send a rest request to the server at the same time.
 Also changed .htacces to mask the request instead of redirecting it and to append existing query parameters instead of overwriting them, by adding the QSA-flag close #86
Did some fixes in app.js for our ls_rest_adapter implementation fixes #86
Merge pull request #87 from Canbanizers/data_persistence_handling
