Back button breaks when tokens start with /

I know support was improved for tokens that start with '/' in 1.1-SNAPSHOT. I am using the latest version.

The back & forward button doesn't work after clicking a couple of links.

After looking through the gwt-pushstate code I think this may be too complex for a simple fix and recommend simply not supporting tokens that start with "/". Perhaps adding some asserts to enforce this.

To help I'll be uploading a version of RouteTokenFormatter later today that isn't required to begin with a slash (this will also fix ArcBees/GWTP#233) and a PushRouteTokenFormatter that explicitly requires that tokens don't start with a slash.
