Configuration make-over about lxmppd HOT 5 CLOSED

I would really prefer it not be code. That is, it should always be possible to 
display it in an admin web interface. (We can't do have that if the 
configuration 
supports code constructs like loops, functions, etc)

Assigning to waqas, because he deserves it :)

You had 2 issues assigned, I had none. Just erm, helping you out by 
re-assigning to
myself :)

Still need to support more formats, but this is taken care of for alpha.
