fixed errors that occurred on ticket changes or deletions by changing some  conditions in the default dialog cancel button and close function fix #89
Updated private_canban_routes model function to find all tickets and boards and return their quantity as model properties and moved the transitioning to the afterModel hook.
Based on this I have refactored the BoardRoute to create a new board if the returned values are 0 #60
created separate functions for ticket creation and deletion and added an error handling example to createTicket.
updated board.hbs, so the new functions get called #60
added App.TicketAdapter to app.js as example for catching server errors #60
updated styling for the different ticket dialogs #66
