Simplify GUI Creation

[TBye101]

Making GUIs is currently a slow process with lots of boilerplate tasks for a developer, and utilizes hardcoded locations. GUI creation should be simplified to the point where a developer tells some sort of UIContainer what children elements the developer wants to add to it, and this UIContainer auto arranges/resizes elements.

Short term simplification is to do event based elements, instead of making many classes that inherit from elements to use them.
