Intl support & updated requirements

Hm, I don't think I quite get git, cuz it looks like this commit "natively" includes my other commit to remove the WEB_ROOT/APP_PATH/etc.

Unless that's how it's supposed to work??

Anyway, lemme know what you think.

BTW, I had to update py-bcrypt because 2.0 didn't exist when I was restoring the requirements.
