The country/language json files are used for user config settings, so
the "misc" name didn't really make sense. Also moved these to the static
folder to make testing easier.
Executable renamed to "run" to avoid confusion with pip installed script
Updated heroku deploy button to use the heroku-app branch, which by
default enforces HTTPS
Added instructions for enforcing HTTPS on various deployment options,
with note about how this isn't a required task.
Updated setup.py description to use improved app description
