Block generation for twig templates.

[florentdestremau]

Hi, First of all I love your work for this sublime package !

I'd like to know if it was possible to extends twig commands for building blocks, imports, render, if/else conditions and loops.

I'll try to extend it but in case i don't get how to do it i'd like people to know that it would be appreciated :)
