* --mesh (-m) now accepts the interface:alfred_sock syntax to add multiple batman/alfred instances. Also multiple instances can be added at once now. Only one interface can be added without alfred socket support (available since 2014.4.0) though.
* --alfred-sock (-s) was dropped in favor of the new --mesh syntax, which adds the interface to socket relationship
* --vpn (-V) now accepts multiple mac addresses, ATTENTION: update your calls accordingly
* --prune defaults to int now
* --with-rrd was renamed from --rrd, to better reflect its boolean/toggle like state
