1. Add support for requirements to mapper.resource …

   This adds support for ``requirements`` option to mapper.resource,
   which makes it possible to restrict matching in urls (most often
   useful for capturing variables with path_prefix).
   
   In OpenStack Nova we've used the prefix_path on Mapper.resource to
   specify additional variables we want to capture (specifically
   {project_id}). Project_id is a uuid. When trying to restrict
   project_id to only valid uuid format a couple of issues were exposed.
   
    - #1 '/{project_id:[a-f0-9]{32}}/...' builds an incorrect regex
       because of the nested {}
   
    - #2 the preferred method that works on connect() to pass
       requirements doesn't work here (requirements are reset to only an
       id match)
   
   That leaves us with having to build a custom project_id match with 32
   [a-f0-9] strings appended for every resource added to get the support
   we need without effectively vendoring our own version of Mapper.resource.
   
   This small change to allow requirements to pass through would make it
   possible to get this tighter validation with much smaller regexes.
