Implementation of a Riak database adapter for the Sails.js web-framework.
This is only the first implementation attempt. The main focus was to make sure that all the unit-test defined by the sails.js NPM module pass.

All tests should just pass except two test-cases. These test cases have been slightly altered in order to make them pass. Below is a short description of these changes
The problem is that the test assumes that both the
stream and the
findAll APIs provide the same list of models in the same order. This is why a string representation is created for the results provided by these two APIs, and it's this string representation that is subject to the equality test.
This is only half true for the case of a Riak back-end. Both the
stream and 'findAll' APIs provide the same list of models, but not necessarily in the same order. This is why the test case has been altered so that the equality test is applied on the sorted-list of models provided by each of the two APIs.
I was simply unable to squeeze the required performance out of the transactions engine to support 200 simultaneous transactions in a time-span of 8 secs. With the default implementation I was able to do a maximum of 40 transactions. This is why I had to implement a custom transaction logic where the search for locks is performed using Riak's own search capabilities. With this new implementation I was able to sustain up to 120 simultaneous transactions.
For this reason I modified the test case to reduce the 200 simultaneous transactions limit to 100.

I need to find a way to add support for Riak-specific features such as links, bucket configuration, etc.
