Remove weblint (and august)

Weblint is broken (won't even start up). It uses unsupported perl
syntax, requires newgetopt.pl which was removed in perl 5.16 (2012), and
find.pl which was removed just around the same time. Past that, the port
is a mess (it's a perl script, and doesn't even depend on perl), and
upstream has disappeared. There's no reason to keep it around at this
point.

www/august (last release 2001) depends upon it, so remove that too.
I removed the Bluefish WEBLINT option, so bumped PORTREVISION there.
