Makes it easier to contribute and accept translations.
Does add a new dependency on installation from source, polib. This is
not made mandatory because not all users will want translations.
polib has no further dependencies and can be installed anywhere
LinkChecker can, using pip too.
Add release process step to check polib is installed
The Wheel still includes translations. Recommend install from PyPI in
the README.
Translations were being compiled in setup.py until 2014, using a bundled
copy of msgfmt.py.
