" This patch renames the existing received-*-msg signals
to receiving-*msg to fit the naming of other signals
where a pointer to the message is passed (writing,
sending, displaying)

It adds new received-*-msg signals which are emitted
after the receiving signals, in line with the other
conversation signals (wrote, sent, displayed)

This is necessary to allow plugins which depend on the
final received message to work alongside plugins which
may modify the message.

One known example of this is festival-gaim alongside
gaim-encryption - festival-gaim would try to "speak"
the encrypted text:
http://sf.net/tracker/?func=detail&aid=943216&group_id=89763&atid=591320

I've tested this with gaim-encryption and festival-gaim
(locally modified so gaim-encryption uses the receiving
signal and festival uses the received signal)

All in-tree users of received-*-msg are updated to use
receiving-*-msg if they do modify the message, the
conversation-signals documentation is updated, the
signals-test.c & signal-test.tcl plugins are also updated." --Stu Tomlinson
