Title: Adding "provides" as a global member of the CouchDB environment

Just a minor thing I came across running my own tests for a CouchDB API I have.

`provides` is provided in the case of both [`_show` and `_list` functions](http://wiki.apache.org/couchdb/Formatting_with_Show_and_List), so I added it as part of the `couch` environment. Included are also the applicable changes to the unit tests. :)
