add ui-bootstrap and materials

2 new things :

- Add an optional question if you choose Bootstrap to ask if you want to add UI-Bootstrap, AngularStrap, the standard JS files of Bootstrap or nothing

- Add Angular Material in the UI Framework question
I may be wrong, but I think there should be no else as javascript file must be excluded from wiredep when using ui-boostrap or angular-strap. (I'm working on foundation equivalent)
