Unicorn is a Rack HTTP server for Unix and fast clients

Small fixes and documentation are the focus of this release.

James Golick reported and helped me track down a bug that caused
SIGHUP to drop the default listener ( if and only
if listeners were completely unspecified in both the
command-line and Unicorn config file.  The Unicorn config file
remains the recommended option for specifying listeners as it
allows fine-tuning of the :backlog, :rcvbuf, :sndbuf,
:tcp_nopush, and :tcp_nodelay options.

There are some documentation (and resulting website)
improvements.  setup.rb users will notice the new section 1
manpages for `unicorn` and `unicorn_rails`, Rubygems users
will have to install manpages manually or use the website.

  Edit: That's not entirely true, I screwed up the package but
  you can get them from http://unicorn.bogomips.org/unicorn.1
  and http://unicorn.bogomips.org/unicorn_rails.1

The HTTP parser got a 3rd-party code review which resulted in
some cleanups and one insignificant bugfix as a result.

Additionally, the HTTP parser compiles, runs and passes unit
tests under Rubinius.  The pure-Ruby parts still do not work yet
and we currently lack the resources/interest to pursue this
further but help will be gladly accepted.

The website now has an Atom feed for new release announcements.
Those unfamiliar with Atom or HTTP may finger unicorn at bogomips.org
for the latest announcements.
