As per version 1.25 of XEP-0045, use the room JID as the 'from' address
for <delay/> elements also when the room is non-anonymous, and specify
the original JID of the sender as an XEP-0033-style tag instead.
Closes#465.
Provide a simpler interface for adding <delay/> and <x/> timestamps to
stanzas. This also makes sure that only one <delay/> tag and one <x/>
tag is added to a given stanza.
Make sure persistent rooms are stored to the database. Without this
change, a room got lost if the 'persistent' flag was handed over to
mod_muc:create_room/5 and the server was then restartet before any
activity took place in that room.
