Subject: Begin web app frontend in PHP.

While I'd like a command line client for retreiving information and
scripting stuff based on the db contents, a web app is convenient for
the less common stuff like adding and editing data.

The web app could also have been done in rust, however, I feel php is so
convenient for simple web stuff that I think it makes more sense this
way.
