vcs: Restructure vcs module

Just like writing and qutebrowser modules, restructured the version
control software module to make more use of dotter's ability to
precisely link files. All contained programs have a top-level directory
and all the files that correspond to that specific software lie beneath
in the directory tree.

 I sign all my commits by default, so take out the corresponding lines if you don't, or exchange it with your gpg key.
+Similarly for jujutsu, change the identity and remove the lines concerning gpg signing if you don't use it.
 
 Git will rewrite any remotes using http(s) to use the ssh notation for pushes to github and gitlab so that, even if you set up the repository using an https url you can utilize your usual ssh key for pushing.
