declare/require functionality

[Locke Birdsey]

We need a way to easily create Panes in separate files which would require the use of requirejs, browersify, etc. However, these either require Node.js or prevent passing of arbitrary values. A solution to the latter problem would be creating everything as modules (which would require a silly amount of work).

Using order HTML script tags could work, however will break when circular dependencies are encountered.

tl;dr Too annoying to use requirejs or others, will continue messing around in a single file :(
