Allow configuring 'include' option as an array in sass-lint.yml

[mischkl]

We have our SCSS files in two separate folders, one for global styles and another where it is co-located with Angular components. From what I've seen in projects at two different companies this is a pretty typical file layout. In order to configure sass-lint to only see the actual paths we need, the only possibility at the moment is to specify include: '**/*.scss' and add everything else to the ignore list - but that is counter-intuitive and not really best practice since it's prone to breaking if anything in the project structure changes.

IMHO this asymmetry between include and ignore should be eliminated. include should be specifiable as an array just like ignore, thus significantly reducing the configuration complexity (because ignore can in many cases simply be ignored). ;)

I'm +1 this, as I encountered a scenario where I would use this today.

I'm working on this as we speak, should be with you for 1.8
