JDF-407 Remove Errai and GWT from TicketMonster Tutorial

Replace Errai and GWT with a poller based HTML5 solution.

New services were written for obtaining the performance status, and to modify the bot state. New Backbone.js views and model were created.

The polling strategy used is not a long-polling solution. It is timed to occur at the same interval for the Bot (3 seconds).

What needs to be completed:
- [ ] Updates to the TicketMonster guide
- [ ] Consideration for a long-polling solution
- [ ] Review of the JAX-RS resources created. The Bot resource is not RESTful since it is a direct port of the earlier RPC endpoint.
