Added Quiz Templates & Paid Plans

Based on the feedback of first users I decided to add a ton of out of the box quiz templates for people to use.

While some people want to spend time creating their own quiz, not everyone has the time and want something quick.

To go along with this I also added the first basic premium plan for $10 a month, which gives users access to pre made quiz templates and a premium version of the editor which lets them build image quizzes.

I also sped up the application to make questions and answers appear faster as this was something I had feedback about.
