www/ruby-rack-contrib: update to 2.0.1

2.0.1						2017/12/08

Multibytes bytes again!

This is a bugfix release, which fixes a Rack 2 incompatibility in
Rack::NotFound, where the wrong value for the Content-Length response
header was calculated (#143).

Thanks to Kazuhiro NISHIYAMA (@znz) for the bug report, and Joe Francis
(@lostapathy) for the fix.

Rack 2.x Support Is HERE!

Thanks to the hard work of Skye Shaw, amongst others, this release of
rack-contrib supports Rack 2.x. Unfortunately, it only supports Rack
2.x; if your application is using Rack 1.x, you should continue to use
rack-contrib 1.x.

The non-backwards-compatible, user-visible changes are:

* Drop support for Ruby versions less than 2.2. Rack 2 does not support these
  older releases, so there's no benefit in our doing so.

* Rack::NestedParams: switch to using Rack::Utils.parse_nested_query to parse
  request bodies, which handles repeated element keys differently.  See #92.

* Rack::Sendfile: removed completely. Rack core provides a middleware of the
  same name that is much better, and more actively maintained, and you should
  use that instead.

* Rack::AcceptFormat: removed completely, because it is terribad.
