Reorganize module loading.

We now use webpack instead of SystemJS, effectively bundling modules
into one file (plus commons chunks) for every entry point.  This results
in a much smaller extension size (almost half).  Furthermore we use
yarn/npm even for extension run-time dependencies.  This relieves us
from manually vendoring and building dependencies.  It's also easier to
understand for new developers familiar with node.

-/*
- * Meta Extension
- *
- * Sets default metadata on a load record (load.metadata) from
- * loader.metadata via SystemJS.meta function.
- *
- *
- * Also provides an inline meta syntax for module meta in source.
- *
- * Eg:
- *
- * loader.meta({
- *   'my/module': { deps: ['jquery'] }
- *   'my/*': { format: 'amd' }
- * });
- *
- * Which in turn populates loader.metadata.
- *
- * load.metadata.deps and load.metadata.format will then be set
- * for 'my/module'
- *
- * The same meta could be set with a my/module.js file containing:
- *
- * my/module.js
- *   "format amd";
- *   "deps[] jquery";
- *   "globals.some value"
- *   console.log('this is my/module');
- *
- * Configuration meta always takes preference to inline meta.
- *
- * Multiple matches in wildcards are supported and ammend the meta.
- *
- *
- * The benefits of the function form is that paths are URL-normalized
- * supporting say
- *
- * loader.meta({ './app': { format: 'cjs' } });
- *
- * Instead of needing to set against the absolute URL (https://site.com/app.js)
- *
