Get Rid of the $

[rameshvarun]

There are three ways to get rid of the $ requirement, but all have trade-offs.

1. Install exports onto globalThis. This could clobber built-ins and break things For example, if someone writes the code export const postMessage = () => {}, the worker won't be able communicate with the main page anymore.
2. Auto-destructure values from $, eg add "const a = $.a" to the prelude. However this would make values early bound, whereas we want them to be late bound (lookup on use).
3. Use Babel to transpile unbound globals, eg "console.log(a) -> console.log($.a)". However, it means that newer JS syntax can't be used in a notebook without upgrading it's Babel version.

Already implemented 3 in 283d100, but removed since I didn't have time to fully test.
