Title: Relaxed unnecessarily strict rack dependency to ~> 1.2

oauth2 uses 2 methods in the Rack gem, both of which are located in lib/rack/utils.rb. The comparison at https://github.com/rack/rack/compare/2ed515786322059f568c8a9df77a6e4b70f09225...e932c585dd1c97e504697c41ce9a4d638275ae02 shows that the only changes between 1.2 and 1.4 in these methods are performance improvements or security updates which are not relevant here, as we are not acting as a server.
