Create a UI simulator

[stevieb9]

It's hard scrolling through every element to see where things go, then to modify it. If there was a single function to create each type where we just send in a reference and some numbers, we could manage the layout in a table

• Create simulator UI
• Create tools to automate basic tasks (move blocks of elements)
• Add documentation for new simulator and all tools to dev docs
• Make ui.json an array, and edit all code to reference the first element instead of the name directly. This way, the file always stays in the same order
