mss --version

[Reimar Bauer]

I want to change that the call mss --version only shows the version information and does not start the UI

The benefit is that I can do this call also on conda test. And we see by succeeding that all dependencies are available.

added -v, --version to the gui call and also simple conda test for mss into meta, fixes #153
