Git commits, on push, will be signed by default (just like my git
configuration itself) but *not* every change is signed since that is a
hassle with the working copy technically also being an ever changing
git commit.
Additionally, added a private-commit option which will refuse to push
commits beginning with 'wip: ' to any remote, which is not super useful
for my current use cases but also a nice feature and fun to experiment
with for the future.
The default log invoked when hitting `j` is now composed of the working copy history as well as all
ancestors, recent commits to visible heads and the trunk.
`jl` shows the same view, only as oneline commits.
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.
