Display version number of Internet.nl code in frontend

Display version number of Internet.nl code in frontend, e.g. in footer.

As discussed during a meeting this could reflect the latest tag release (e.g., v1.3.2).
This would make sense only if all the live versions are done by checking out version tags.

If a version needs to go live that is not yet part of a full release (e.g., updating straight from the master branch), or different development versions are live, then using the git commit hash would be easier to understand.

This could be integrated in the make translations command (necessary while deploying) to get the version string from git and replace it in the translations/*/main.po files before generating the django files. That would mean that a distinct place holder needs to be in those files for a trivial text replace logic.
git describe --tags and git rev-parse --short HEAD could prove useful to getting the version string.

Then optionally the displayed version could be a link to <github_address>/Internet.nl/blob/<tag or commit hash>/Changelog.md.

@mxsasha Could we:

1. align the version info to the right (currenty it is directly after the tagline "Internet.nl is an initiative of the Internet community and the Dutch government.");

2. make sure that for smaller screens/windows the version info is placed under the mentioned tagline on a new line.

A solution would be wrapping

Internet.nl/interface/templates/base.html

Line 97 in a1dc18f

v{{ "VERSION"|get_settings_value }}

with a

<div class="version">..

and then add some

  footer .wrap .version {
    float: right;
  }

in the @media (min-width:800px) block and add a

  clear: both;

to the footer hr style:

Internet.nl/frontend/css/style.css

Lines 1348 to 1351 in a1dc18f

	/* footer */
	footer hr {
	background: white;
	}
