This adds a separate Markdown document comtaining a table with all
available ports, including name, version number and website.
This should make it easier to get an overview of what's available or
learn more about ports one is not familiar with, as well as checking the
current version of each port (many are outdated by now, and the version
being hidden in the package.sh script doesn't improve that situation)
and spotting ports with no defined version (i.e. install from the main
branch), which can break easily and should be avoided.
Please keep this list in sync when adding or updating ports. :^)
