Standalone Quizzer Productization

Big news is that after a few years I finally have all the new features into the standalone quizzer. I just finished the testing system yesterday. I'm starting on a new path to make some flashcard products around the quizzer and begin refining. I'm going to start with Spanish since I already have that content. There are still a lot of loose ends and cleanup that will be happening, but the major structure is done and it's on the the next steps.
