Allow `python setup.py develop`
Preparing to allow extra getJSON param "language"
Can .configure() language other than 'en'

It acts globally for now
All data calls to TMDB got language param

All calls to .getJSON() that gets some info, have now a 'language'
keyword, that overwrites globally configured one.

Btw, the default is 'en' for now.
