Add --tests --list and --vendor flags
Add --tests --list and --vendor flags

The vendor bundle will no longer be generated by default. Pass in the
--vendor flag to generate the vendor bundle and copy other static
assets to the Django static folder.

Since the vendor bundle rarely changes, this should make the primary
bundle task much faster.

Likewise, the test bundles are no longer created by default. To
generate the test bundle, use the --tests flag.

The --lists flag will list module dependencies instead of generating
any bundles. It's helpful to determine which third-party libraries are
included in our main bundle so we can yank them out into the vendor
bundle.
