PyBabel extract, update, compile instructions are missing

[therealmarv]

This is missing in the docs.

• PyBabel commandline interface: http://babel.pocoo.org/docs/cmdline/
• Got a description on how to update PyBossa translation files for different languages here: https://github.com/PyBossa/pybossa/blob/master/doc/translating.rst
• But no description on how to extract initially. I used #661 for extracting, updating and compiling language files:

My approach to update most of the language files. Go to pybossa directory where pybabel.cfg is inside

pybabel extract . -F babel.cfg -k lazy_gettext -o translations/messages.pot
pybabel update -i translations/messages.pot -d translations
pybabel compile -d translations

@therealmarv can you add those instructions to the docs and close this issue?
