2.1.12 statistics option and tinysvcmdns bug fixes

• A new command line option has been added: --statistics, so you don't have to put the program into verbose (-v) mode to get the stats.
• tinysvcmdns is a zero configuration (zeroconf) service you can use if you don't have a system-wide zeroconf service, such as Avahi, already running on your system. This release fixes a few bugs in the tinysvcmdns implementation. You should not use tinysvcmdns if your system has a zeroconf service already running.
