Add message correction support for XMPP (#437)

Browse Source 
It works worse than it could be, since message correction in XMPP
works differently compared to other messengers. XMPP replaces old
message with old ID with new message with new ID. Matterbridge
remembers only old ID, that's why you can edit a message from
XMPP to the gateway only once.

Edited messages from other networks to XMPP are handled correctly
though.
