Use it strictly with the last updates from node-cryptonote-util

This option would be nice to add.

@fancoder As far as I can see most of the latest merge mining code is included in the node pool, but how do you launch the pool to be able to merge mine two coins at once? I've been fiddling with this for weeks and have yet to find success. Thanks
