Run this script from the root of the repository to update all translations from transifex.
It will do the following automatically:
- create a transifex configuration file
- fetch all translations
- post-process them into valid and committable format
This is a project-wide configuration file and should be the same for
everyone.
Also remove mention of creating it yourself from the translation process.
Update current translations, and add new languages:
- es_MX: Spanish (Mexico)
- pam: Kapampangan
Also update translation process for autoconf-based build system.
