Allow abitrary options to be passed to a route

This is what I use in my app, the reason being that my layout contains the breadcrumb template, which generally appears on every page. However - certain pages instead use the last entry in the breadcrumb for the title tag, but hide the visible navigation on the page. An example of a page like this is the dashboard page.

Using options: {} in routes such as this I can do options: {breadcrumb: false} and use that in ng-show in my template. 

This allows options on every route, and defaults its contents to simply {}
