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.
