Enable error code transform per package

Currently we're not consistent about which packages should have their
errors minified in production and which ones should.

This adds a field to the bundle configuration to control whether to
apply the transform. We should decide what the criteria is going
forward. I think it's probably a good idea to minify any package that
gets sent over the network. So yes to modules that run in the browser,
and no to modules that run on the server and during development only.
