Remapping Guice Servlet plugin modules with a uri-prefix

_From [dhanji](https://code.google.com/u/115972161424102003495/) on January 03, 2009 22:42:49_

For example, if you install a third party ServletModule that maps servlets to a URI that you already
use, Guice Servlet should allow you to remap the third party module wholesale under a path-prefix:

install("/rpc/", new RpcModule());

Now, any servlet mappings in RpcModule are remapped with a path-prefix "/rpc/".

This is a fairly complex feature as it requires a good deal of thinking about regex mappings, path-
info rewriting and so forth. I don't think it will make it to 2.0.
