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.

- * Dependency Tree Cache
- * 
- * Allows a build to pre-populate a dependency trace tree on the loader of 
- * the expected dependency tree, to be loaded upfront when requesting the
- * module, avoinding the n round trips latency of module loading, where 
- * n is the dependency tree depth.
- *
- * eg:
- * SystemJS.depCache = {
- *  'app': ['normalized', 'deps'],
- *  'normalized': ['another'],
- *  'deps': ['tree']
- * };
- * 
- * SystemJS.import('app') 
- * // simultaneously starts loading all of:
- * // 'normalized', 'deps', 'another', 'tree'
- * // before "app" source is even loaded
- *
