Create new v18 release with godbus dependency fix

[peterfraedrich]

godep is unable to vendor coreos/go-systemd because the v17 (latest) release is failing its dependency checks due to #296 .

Thanks for the report. I'm tagging a release as we speak. However I fear that you are observing a different and completely unrelated behavior, judging from your output:

subpackage github.com/coreos/go-systemd does not contain usable Go code

Please note that dep here is telling you that it didn't detect any go package at that path. And it is indeed right, as the top level of this project is not a single package (mostly to insulate cgo usage to a few specific places) and you may want instead to reference one of the real packages in the subdirectories.

In any case: https://github.com/coreos/go-systemd/releases/tag/v18

I'm leaving this ticket open till tomorrow in case @peterfraedrich gets more insights from tracking down the problem.

@lucab little column A, little column B.

v18 works great, thanks for doing that.
