A bunch of fixes to express declaration

- Move Express-prefixed interface names into internal module as
  unprefixed names
- The importing code will use express.Response instead of
  ExpressServerResponse
- Internal definitions can just use Response instead of
  ExpressServerResponse
- Response should extend http.Response to be able to type check .end

Tightened up ValidationOptions

Using a combination of the source code and the documentation at
http://jqueryvalidation.org/validate/ I've tightened up the
ValidationOptions.  NB success remains as any because (AFAIK) it's not
possible to model alternate overloads in an interface with TypeScript (
https://typescript.codeplex.com/workitem/1893 ).
