Rack Release 1.0

[Joon You]

Guys,

Looks like Rack 1.0 release is coming soon, if not this week for
release candidate. Here's a list of features Christian sent out.

* SPEC change: header values must be Strings now, split on "\n".
* SPEC change: Content-Length not enforced anymore, chunking is used
when missing.
* SPEC change: bodies can respond #to_path with a filename to be
served.
* NOTE: String bodies break in 1.9, use an Array consisting of a
single String instead.
* New middleware Rack::Lock.
* Support for nested parameter parsing in Rack::Response.
* Support for redirects in Rack::Response.
* Major update to Rack::Auth::OpenID. [DETAILS?]
* HttpOnly cookie support in Rack::Response.
* Many bugfixes and small improvements.
