ConsoleKit is obsoleted by systemd-logind. Accordingly, port
the current CK code to systemd. In order to be nice to
the Debian people fall back to CK if systemd is not found,
so that the code makes the best of whatever it runs on.
js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.

This commit adds a power menu similar to the one in the fallback greeter
which offers 3 items:
- Suspend
- Restart
- Power off
