Add ability to get a type by fullname (without assembly name) to TypeDiscoverer
Add FullName (name + namespace) to Javascript proxies.  Use for context
info on server calls (e.g. query, readmodelfor, command, etc.)
Put server type information on to generated js proxies to make it easier to
convert them to their server side equivalents.  Fetch type by name from
ITypeDiscoverer.

Tidy up NamespaceMapper a little.
