Deft JS 5 alpha 1

Initial version of Deft JS 5 that is compatible with the Ext JS 5 beta.

While most of the functionality around promises and IoC remains the same, view controllers are significantly different. The Deft ViewController extends the Sencha ViewController. That means that the syntax and behavior for controlling view components is now handled by the Sencha class. See the Ext JS 5 docs for full details on how this should be handled now.
