new feature: send trade notifications via xmmp
User to enter their xmmp server and account details as an option into haveno.
if a trade is taken by someone it notifies the user via xmmp - (perhaps other events too?). Optionally, haveno to display the xmmp address into the haveno chat so the trading partner can send xmmp messages to peer as well if they choose.

I understand there is a mobile app in the works. This feature could still go exist for those are strict with apps they run on their phone.
Messaging like this is important as its not convenient to check haveno all the time for trade activity and it may delay trades if people dont check often.
