Distribute wheel files.

[jpsnyder]

I'm having a difficult time getting this library to compile in Windows. I've tried following the tasks done in the travis configuration files, but it just doesn't seem to be working.

Is there any chance of uploading compiled .whl files to PyPi? This would be super helpful!

I remember it was a major headache to align all the ducks just right under Travis. However the build procedure there is awful (it does not even check the signature / checksum of chmlib, dowloaded via HTTP!), I'm not sure anyone should be using the binary built this way.

Probably the best way to go is to update CI procedure to be somehow sane, and then publish wheels.
