Parse the URL to determine the route instead of using explicitly
specified GET parameters.

http://app-path/<handler>/<action>/<param1>/.../<paramn>

<handler> specifies the	Handler	class to route to.
<action> specifies the Handler method to call.
<param>s are passed to the Handler method being	called.

See 'http://app-path/site/index/someone' for an example URL
routing and parameter passing.
Alter the definition of render to make the layout name the last
parameter.

This approach makes more intuitive sense.
