Find a better solution for global.$

[obuchtala]

ATM we rely on jquery being available globally.

In the browser we need either include jquery via script tag or do this

var $ = window.$ = require('jquery');

On the server we use cheerio, and register it the same way.

It would be better to have a index file serving jQuery or cheerio.

var $ = require('substance/jqueryish');

Find a better name.
