Peter Bengtsson: hashin 0.7.0 and multiple packages

My colleague Andrew Halberstadt stepped up with a great contribution on hashin ( on PyPI ). Now you can install multiple packages in one sweep. Like this:

$ hashin requests Django premailer mincss

And if you need to specify a different requirements file than the default ( ./requirements.txt ) or a different algorithm than the default ( sha256 ) you can do that like this:

$ hashin requests Django premailer mincss --algorithm=sha512 --requirements-file=dev/reqs.txt

or

$ hashin requests Django premailer mincss -a sha512 -r dev/reqs.txt

This is an important change if you were used to typing:

$ hashin somepackage dev/reqs.txt

...because if you continue to do that it's going to try to fetch the hash for a PyPI package supposedly called "dev/reqs.txt".

Thanks @ahal!

Note!The operation is not atomic. So if you do hashin requests somejunk it will hash in the latest requests to your requirements.txt and error on the second one.
