filters fails to install using setuptools

When trying to install filters using setuptools, the following error raises:

setup.py contained an unnecessary reference to LICENSE, and MANIFEST.in was missing.

I committed a potential fix for this issue, but needs more testing. So far the only way I can reproduce this issue is if filters is downloaded from PyPI; I haven't figured out how to reproduce from a local archive yet.

Hey Pedro! v1.3.0 was just released, and it potentially contains a fix for this issue. When you have a chance, could you verify if this issue is still reproducible?
