#17 Add support for systemd's socket activation

[Stefan Bauer]

To allow metalog to be used in a systemd controlled system, it should be able to use its socket activation mechanism. There exist two thorough documents from the systemd author describing the needed changes:

http://www.freedesktop.org/wiki/Software/systemd/syslog

I'll try to provide a first patch for further discussion.
