Added local storage to add tickets view

Tickets you create are stored in local storage until you publis them!

Created new service Lstore. It will check that local storage is available before it stores something. If it is not available it will not use local storage, and just store stuff in scope. The service can be used for all localstorage stuff, not just the tickets view.

A really nice feature for testing with live reload as this othervise means loosing your testdata all the time as they are only in the frontend.
