Ensure routing generator works with non-string keys. [#172 state:resolved]

Make sure that (with recent correction to globbed parameter escaping) non-string
values can still be passed route generation helpers for globbed route segments.

For example, foo_path([1, 2, 3]) should still work for a route like map.foo "*globbed"
by implicitely calling to_s on the Fixnums.
