Implementing a new Question type

There are two main parts: The question that extends from Quizer::Question and the question attempt that extends from Quizer::QuestionAttempt. Each one have a backend part and a frontend part.

I've created two commits were I (kind of) explain the implementation of Quizer::OpenQuestion
