[code-quality] pylint and gtk3

[Zunbeltz Izaola]

Dear all,

I read that pylint can handle the gobject introspection thanks to 
astroid and pylint-brain.
I installed version 1.1 of pylint and py2gi.py is installed in my system.
But, I don't understand how to enable the use of py2gi, because I still 
have the E1101

Instance of 'Box' has no 'pack_start' member (no-member)


Thanks in advance for your help,

Zunbeltz
