When configuring the Git Repo server, we could optionally track one folder
in the root git repo, instead of just the root folder. This was
specifically to address my use case where I have my journals in a
sub-directory. The setup screen was super ugly, though.
Since now I'm in the process of adding folder support because of #18, I
can remove this hack. It simplifies the code a lot.
This is only shows if there are subFolders with '.md' files. This
feature is super important for me as it allows me to finally dogfood
this app and use it
This patch just adds the screen, but the subFolder selection
currently doesn't do anything.
For now just create a local git repo and commit all the changes over
there, we're going to allow the user to first see the app and use it
however they want, and later connect it to a remote git repo.
This commit breaks the app, as the on-boarding screen is no longer
connected so you cannot push to a remote app.
