Added logging just before the outgoing invocation

#2754
Updated topic count to 5

Parse responses based on the type of the response, not ajaxDataType

- prevents bug where WS messages wouldn't be parsed with JSONP enabled

#2768
Test to verify that WebSockets work with JSONP forced by the JS client

#2768
Use available types from ReflectionTypeLoadException when finding Hubs

- provide better tracing when Assembly.GetTypes() throws

#2712
Decided it was better not to use types from ReflectionTypeLoadException

In practice, these types are often not usable by the HubMethodDispatcher,
e.g. a FileNotFound exception can be thrown when compiling an Expression
Added a trace listener for initialization errors/warnings to the sample

- So far this only listens to the SignalR.ReflectedHubDescriptorProvider key
Changed the way we access hub proxies
