Call for 1.1.0 release

[Joshua Peek <josh@joshpeek.com>]

I'd to cut a 1.1 release before the new year. I'm going to put in the
work for the release notes and actual gem push. Now that we are on
Gemcutter, the entire rack core team has push access.

Heres an overview of the major changes:

* Relaxes SPEC to allow subclasses.
  - This is the major change I want to get out there. Right now Rails
2.x needs to monkey patch Lint to work around this.
* Refactored rackup into Rack::Server
* Removed Auth::OpenID
* Nested parameter and multipart generation improvements to Mock
* Pull in some useful contrib middleware: Config, ETag, Runtime,
Sendfile
* rack.logger extension specification
* Various bug fixes and optimizations

Please test rack/master and make sure your libraries are ready.

I'd like to get a +1 from all the rack core members before anything is
released.
