Webpack Watchers

[spalger]

It seems that if you make changes to multiple files, and then refresh the page, it is possible that only the first file will be included in the build.

To add my comment from the linked issue, sometimes, it doesn't even see the change in a single file.

I tracked down my issue to the watchpack module and created a pull request there: webpack/watchpack#17

If I make webpack use the old watcher, I also don't have my issue. I don't know what other issues it might cause though.

To go back to the old watcher, just add "new webpack.OldWatchingPlugin()" to the plugins array in src/optimize/BaseOptimizer.js

As far as I can tell this was fixed in #6395. Beyond the the upgrade to webpack2 (once it's out and tested) will mean we can start using the feature they have which supports this usage pattern.
