Merge branch 'main' of adrian.geek.nz:/srv/git/hurl into main

Release HURL 0.2 exposing tables & parameterizing initial CSS.

While I was at it, I allowed useragent CSS to style errorpages specially.

Release v0.1 decoupled from Rhapsode, with CSV/TSV & refined tablesorting!

Extract MIMEtype parsing library from Rhapsode.
