New port: www/miniserve

Miniserve is a small self-contained ad-hoc HTTP server that allows
you to quickly serve some files over HTTP.

Features:

• Easy to use
• Just works: Correct MIME types handling out of the box
• Single binary drop-in with no extra dependencies required
• Authentication support with username and password
• Fast and highly parallel (thanks to Rust and Actix)

It is an interesting alternative to some popular solutions:

• Python's built-in webserver: Needs to have Python installed, is low performance, and also does not handle MIME types correctly in some cases.
• netcat: Not as convenient to use and sending directories is nontrivial.
