impromptu: Incorporate feedback from daniel for muc options

Adding missing MAM bits, removing the allowpm restriction, as clients
should already be using realjids when available.

I am leaving allowinvites for now as I think that should be in there,
but we can align ourselves later on if necessary, I'm not totally
against the idea.
