Wombat rewriting causes web workers to fail

[mpbrucker]

As seen in ec2b7ce:

Because the module code is run within an iframe where Wombat is active, attempts to create a new Worker() using module code will fail because Wombat will rewrite the file location, thinking it's referencing a collection-specific archive resource as opposed to a static file.

One workaround I've found for this is to convert the worker function into a Blob, and generate a URL for it--that way, Wombat won't rewrite the URL in the same way. The implementation can be seen in #8.
