include() should support longform-syntax

[stmh]

It would be great if include() can support also the "longform"-include syntax of twig, as this will give us more flexibility and avoid collisions when using more than 2 hierarchy-levels.

Here's an example of a possible collision:

long-form	short-hand
@components/one/two/three	components-three
@components/two/two/three	components-three

Thanks for the suggestion! Will look into this as soon as I find some time.
