[ANN] unicorn 0.93.0

[Eric Wong]

More small fixes and documentation improvements in this release, things
have settled down a lot since 0.90.0 in August and we've mainly been
focusing on documentation, minor UI improvements and the occasional
minor bugfix as they get reported.

Changes:

  The one minor bugfix is only for Rails 2.3.x+ users who set the
  RAILS_RELATIVE_URL_ROOT environment variable in a config file.
  Users of the "--path" switch or those who set the environment
  variable in the shell were unaffected by this bug.  Note that we
  still don't have relative URL root support for Rails < 2.3, and
  are unlikely to bother with it unless there is visible demand
  for it.

  New features includes support for :tries and :delay when
  specifying a "listen" in an after_fork hook.  This was inspired
  by Chris Wanstrath's example of binding per-worker listen
  sockets in a loop while migrating (or upgrading) Unicorn.
  Setting a negative value for :tries means we'll retry the listen
  indefinitely until the socket becomes available.

  So you can do something like this in an after_fork hook:

      after_fork do |server, worker|
        addr = "127.0.0.1:#{9293 + worker.nr}"
        server.listen(addr, :tries => -1, :delay => 5)
      end

  There's also the usual round of added documentation, packaging
  fixes, code cleanups, small fixes and minor performance
  improvements that are viewable in the "git log" output.
