v1.3.0-rc.1

New features

• Process details dialog:
  Now from the Processes tab, after clicking on a process you can click on an icon to view details of a process.
  You can monitor memory mapped files, opened files/sockets and memory consumption among other things.

• System rules:
  There's a new configuration file /etc/opensnitchd/system-fw.json where you can configure system rules to block or allow connections.
