I want to publish the _20125_ Status application to an F-Droid
repository to make it easy for Tabitha to install and update. F-Droid
repositories are similar to other package repositories: a collection of
packages and some metadata files. Although there is a fully-fledged
server-side software package that can manage F-Droid repositories, it's
not required: the metadata files can be pre-generated and then hosted by
a static web server just fine.
This commit adds configuration for the web server and reverse proxy to
host the F-Droid repository at _apps.du5t1n.xyz_.
