Remove step that is unnecessary for getting started with the simple minimal HTTP server now provided.

Note that this does not remove the step entirely from the documentation, just from the simplified "getting started" procedure. This topic is still covered in the full installation instructions at http://openig.forgerock.org/doc/gateway-guide/#jetty-cookie-domains

Fix MapResolver behaviour, Resolver.get() is supposed to get the value and return UNRESOLVED if the value is unknown.
Now, we only return a value (maybe null) if the required key was contained in the Map.
Old implementation returned null when the key was unknown AND when its value was null.
