Added TryExecute method to the IMessageExecutor interface
added the new Respond cascading message.  Closes GH-151
fixed the ChainInvoker mechanics so that it is using the continuation to avoid sending outgoing messages when the chain fails
added IImmediateContinuation and encapsulated the IOutgoingSender within ContinuationContext
finished the ContinueImmediately.With() returns on message handling.   Closes GH-156

Fixed issue with namespaces for deserializing xml rhino messages.
Fixed downstream failing test for LQ requeue behavior
Added translation for LQ specific sending options
Fixed in-memory code to still work after InMemoryTransport is cleared.  This was preventing the in-memory transport from working in StoryTeller, which would call ClearAll before each test.
Fixed cleanup of in memory queues so they aren't reused after being disposed.
Attempt to fix a test failing only on the build server.
