Refactored tutorials, but missed chapter goal.

Today's TODO:

• load tutorials from db
• finish csharp basics chapter 1
• (optional) write a script that saves steps per branch

It has taken an insane amount of work, but I've managed to refactor everything so tutorials are generated from the separate directory, imported into the db using a script, and then loaded on the frontend.

I still need to:

• set up step changing
• update the script so it creates the branches automatically
• add support to driver for multiple repos
• finish chapter 1

Unfortunately, despite my best efforts, I wasn't able to finish today. I still need to update the driver and finish the chapter

I hadn't accounted for this much infrastructure work, so I missed my goal of one chapter per week.

Hopefully I can make up for it next week.
