smart watch

[chmontgomery]

As a developer, I want to make changes to a file and have them built into its associated bundle automatically and as quickly as possible. This means, when I change one file I only want one bundle built: the one that contains my new change. All other bundles should be left as-is.

To accomplish this, first the ability to run bundling against one named bundle must be added. Then, gulp.watch can be added to watch the list of files for that bundle.
