#48 Need a way to specify more conditions for expected responses

[Matt Paulin]

Currently RAMP specifies what the responses to a
message will be; we should probably extend that by
having an additional field for what the responses to a
message might be. For instance, entering a room will
always give you a lot of messages. But, it now might
also result in the server sending this new message. I
don't think it makes sense to integrate into RAMP
exactly when all these messages will be recieved,
though, perhaps a freeform description field would let
us do that.

Also, we need a way to let RAMP show how one set of
responses go to the sender, and another set of
responses to go other users. Not sure how to do that.
