The Makefile has to be modified to handle tin in a particular fashion,
because Tin removes and then rewrite its whole configuration file after
closing, instead of only modifying the file.
A symbolic link to its whole configuration folder is therefore the only
manageable way to keep the configuration linked.
To ease the addition and removal of packages, some rules were added to
deal with those specially.
I still need to figure out how to stop repeating myself when linking and
unlinking unconventional packages (such as `scripts`).
Instead of running `install.sh` to link all my packages, I split the
configuration into its CLI components and packages that need a Xorg
display server set-up.
This uses the `bootstrap.sh` script to make sure the needed dependencies
are installed. The `Makefile` can install all the packages or CLI ones
only.
