license: Generate a license and send it in HTTP response

If the purchaser coming from POST params is found in the database,
generate a license for the purchaser, zip the license, and send a
response containing the zipped data.

zip:
Change the writer input to a mutable reference to enable us to use the
zip data when writing to the response. Otherwise we get a borrow error.
