Subject: [PATCH] Remote IMC2 channels can now be listened to via IMC2
 bindings. For this to work, create an IMC2ChannelMapping object with the
 channel you'd like to serve as the gateway to the remote IMC2 channel. Enter
 the IMC2 channel's name as the imc2_channel_name field and make sure the
 object is enabled. Any incoming ice-msg-b packets directed at your chosen
 channel will now be emitted to the appropriate channel as if it were local,
 with one difference: the user name is sender@origin. Sending messages is
 hopefully soon to follow.
