Subject: Added new infrastructure support for REST webservices.   By default
 application/xml posts are handled by creating a XmlNode object with the same
 name as the root element of the submitted xml. M$

 ActionController::Base.param_parsers['application/atom+xml'] = Proc.new do |data|
    node = REXML::Document.new(post)
   { node.root.name => node.root }
 end

 XmlSimple and Yaml web services were retired, ActionController::Base.param_parsers carries an example which shows how to get this functio$
 request.[formatted_post?, xml_post?, yaml_post? and post_format] were all deprecated in favor of request.content_type [Tobias Luetke]

Closes #4081
