Subject: support rack 2.x
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

This requires updating to unicorn 5.1+ to relax the rack
requirement.  Unlike unicorn, Rainbows! is considerably
larger and cannot function without rack installed.

There were no code changes required to pass the test suite;
but some other optional gems needed to be updated for testing.

Support for async_sinatra is no longer tested as that is tied
to rack 1.x; but the remaining EventMachine-dependent parts
remain tested.

Thanks to Julia López Aladro for reminding us on the mailing list:
