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.

+Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),

 ## API
 
-### objectAssign(target, source, [source, ...])
+### objectAssign(target, [source, ...])
 
 Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.
