Clean up, refactor, and functionalise codebase

[Paulj1989]

Problem

The app was put together very quickly and that required some (many) corners to be cut. We now have a pretty significant codebase for what is a relatively small app. We need to clean up the mess!

Proposed Solution

• Refactor code
  • Turn code in to functions
  • Modularise code
  • Cleaner, more explicit conditionals (where conditionals are necessary)
• Consider cleaner, smarter, quicker ways of doing things
