Moved to Postgresql for development and test.
Added random function to Spark.
Added random functionality to Idea, Jawns controller, along with appropriate specs for both Idea and JawnsController.
Ran bundle update.
Removed unnecessary check if seed == 0. Seeds are allowed to be 0.
My bad, seeds are allowed to be zero, but the seed parameter has to be set. Updated JawnsController if statement to reflect this, and to fix failing specs.
