Clean up JS

[rupl]

After leaving this codebase alone for a while and coming back to it, I realize it's bordering on disaster. Very unorganized, tons of globals, and config is spread across several places.

I'm positive that pieces of the functionality only work as a side effect of the (lack of) organization. For the sake of my own dignity and also to ease future improvements, it needs to be cleaned up and reorganized.

• [x] lint the codebase. sheesh. f60ebc3 / f708bb0 / 03852d1 / 1912a1a
• [x] separate vendor scripts a0cb372
• [x] create a namespace busta f03e9bf
• [ ] create proper modules for our high-level components: shapes, users, room, controls
• [ ] replace basic gulp task with a JS bundler

Preemptively labeling this a bug since it will certainly surface a few :bowtie:

after over two years of stagnation I've decided I'm officially bailing on this and rewriting in Vue. It was a valiant effort but the goal of this PR was to accomplish something that is a well-paved cowpath at this point, and it's definitely not my force.

OTOH I love Vue and it does a ton of the stuff I knew I wanted but had no idea how to accomplish. I can probably rewrite the whole app in like 20% of the time I invested in getting this PR to the halfway point it was left in. Plus then I'll have a simple, stable method to apply pluggable functionality and make it configurable beyond my wildest dreams!
