feat(route): Add support to catch-all parameters in routes

This allows routeProvider to accept parameters that matches substrings even when they contain slashes if they are prefixed with an asterisk instead of a colon. For example, routes like edit/color/:color/largecode/*largecode will match with something like this http://appdomain.com/edit/color/brown/largecode/code/with/slashs.
