Allow upload of zipped hospital price file

Here's a patch that seems to work and has a reasonable amount of test coverage. I'm not confident there aren't bugs or security concerns lurking in here though.

In my manual testing I was able to upload an xml file that zipped to 25MB and extracted into a 500MB file. The system has a max upload of 100MB. Unfortunately, memory was getting exhausted while trying to serve the contents of the file from the HPT controller. That was resolved by refactoring the controller a bit. But it may be that some files (1GB?) are way too big for even that refactored approach.

Ah, the patch won't apply here because it has some zip files included for use in the tests.

The tests pass locally. And if committed, there won't be any trouble running tests on d.o. I had this problem with the crossword module a few times.
