Add option to configure Application channels

As discussed in #1321, configurable channels for applications will allow
multiple applications to exist on the same page without picking up each
other's events.
Prevents AppRouter._processOnRoute() passing "undefined" to _.invert() when appRoutes is configured only via constructor.

If appRoutes is configured when AppRouter is extended, "this.appRoutes" is defined.
If appRoutes is configured via constructor, "this.appRoutes" is undefined (held instead at "this.options.appRoutes").

AppRouter._processOnRoute() passes "this.appRoutes" to _.invert(), which throws a TypeError when undefined.

Fixed by replacing "this.appRoutes" with "this.getOption('appRoutes')", which searches "this.options" and "this".
