Package names with a dot do not work with pip >= 8.1.2

[vinodc]

This issue is similar to the one resolved by devpi:

• Issue: Package names containing a dot don't work under DevPI pypa/pip#3666
• Resolution information: http://doc.devpi.net/latest/announce/server-4.0.html#background-on-the-pip-devpi-bug-for-the-curious

When asked for a package name containing a dot version 8.1.2 of pip rewrites the package name with a dash instead (e.g. "foo.bar" becomes "foo-bar"). This seems to work fine on PyPI, but not on [localshop]. Downgrading to version 8.1.1 of pip resolves the problem.

I've confirmed this behavior with the latest version of localshop, by uploading a package with a dot in its name.

This problem is already fixed in the current master branch.
