Add version to footer

[tuxmea]

When opening the HDM webpage I would like to see which version is used.
Version should be based on the GIT Tag or read from a file.

@rwaffen @bastelfreak Feedback from your side?

I remember we discussed setting a VERSION constant inside of a rails inititalizer (something like config/inititalizers/version.rb). This is evaluated once on startup. At this point we could simply shell out to git to try to get a version number.

But I wonder, do we always have a git command and a git repo? Even in docker?

The answer is "yes" 🙂:

we added git some time ago when we had this idea with the seperated git repository to write back data and not change it in the local data dir.
