fix Misc test failures

The Misc test was failing when run as "make input=Misc run" since
test-flags did not include $(build)/extra-dir in the class library,
leading the ClassLoader.getResources test to fail.

Also, the UnknownHostException test was not reliable -- some ISPs
(mine included) return DNS matches for bogus hostnames, defaulting to
the IP address of a webserver intended to help users with name
resolution problems.  That's dumb, I know, but I'm guessing I'm not
the only person with a dumb ISP, and it seems better to just remove
the test than make people think Avian is broken when it's really just
their DNS server that's broken.
push javadoc pages to ReadyTalk/readytalk.github.io instead of gh-pages

This, along with several other changes to the website, should help cut
repository bloat.
