Add version number to Data Explorer's footer

Question

Data Explorer should have a visible version number somewhere, like SO has right corner of the footer (revision: 2010.6.8.1).

This way we'll know when version change and can refer to specific versions in bug reports etc.

Answer 1

Ok, so it took us a while to get there, but you can now see the build/version number of SEDE in the footer, exactly like it works on the core sites.
