Release a High Sierra version

[bartkummel]

I see a "high sierra fixes" branch, which contains various fixes. I hope it is possible to create a bèta release out of this branch? At least one issue is causing me trouble on a daily basis, and it seems to be fixed on that branch: "fix crash when displaying default browser dialog". I would really appreciate a version of Control Plane with that fix applied, even if it is not perfect.

Yes, generally a new release would be interesting @dustinrue - there are some changes since 2014..
