Relax Rack dependency.
Since rack-restful_submit is using only one, the most basic method of Rack, there is no need to be so worried about API change.
Solved bugs that avoid rspec to succeed
- Rails 3 incompatibility with SCRIPT_NAME (J.Provaznik) - Optimalization of splitting PATH_INFO and QUERYSTRING (F.Vollero)
This version supports both concepts at the same time. It means if there's no Restful submit button it also runs MethodOverride to support old functionality.
