Revert "swapped riak base class for trusted_client"

This reverts commit 3d4fbbfad9e5a872d1eb041d62d4059cb1dd2e26.

Conflicts:
	lib/riak.js
updated test script to match test framework used in tests (mocha)
riak now inherits from webflow.trustedclient (though a lot of duplicate code still needs to be removed)
removed bucket.keys test since the method no longer exists
tests passing -- still need to check examples and add link making for riak
fixed a reference to utils -- load-practice-data example working
