Nested scopes are now checked before routes

[ViaoV]

Nested scopes are now checked for route matches before individual routes
in the current scope. This was done to allow the "longest" match to
succeed and prevent wildcard routes from catching a route that would
otherwise be completed by a nested route.

Closes #57
