Transifex

Just a few notes.

The script is not completely ready yet, but at least for this first try, it did the job of downloading the .po files, putting them in the appropriate folder, and converting them to .mo files.
I did the commit manually by going to the tmp folder that is created by the script. 

One thing I've noticed while checking for .po files is that the emails of the translators was exported in the file. There is actually an option in Transifex that you have to uncheck if you do not want your email to appear in the translations files: http://prntscr.com/55djwu.
I did a `sed '/^# /d'` on each .po file in order to remove the header comments to avoid publishing these emails for now.
