Overrides/Classes to allow Router in Ext JS 4.2

There are the actual three classes (Queue, Route and Router) in the Ux/app/route/ directory.

There are a few overrides that make things work together. These overrides will not be needed in the official release with the Router in it.

• overrides/Class.js This class is an override to get the config system to work in a controller by prefixing '_' on the actual property. Otherwise the control config would overwrite the control method breaking everything.
• overrides/app/Application.js This override really boots off the initial hash. So for direct linking (someone starting the app with a hash), this will detect this and handle it.
• overrides/app/Controller.js This override is what will connect the routes configured on the controllers to the Router and have the methods executed.
• overrides/util/History.js There were some bugs that I had found in the History class, this override fixes these issues.

A reminder, these overrides will not be needed in the official release that contains the Router.

This app was generated by Cmd and has an example of the routes and refs. This is a simple app, remember you can use the control and listen configs in the config object in the controller.
