Bug#932956: ITP: node-node-sass -- Wrapper around libsass

[Xavier <yadd@debian.org>]

Hi Ftpmasters,

this package embeds some little components and one big (sass-spec).
sass-spec isn't use elsewhere (see
https://www.npmjs.com/package/sass-spec?activeTab=dependents) and
provides only C++ files needed to compile node-node-sass. That's why
none of its files are installed (installed modules are listed in
debian/nodejs/submodules).

Other little components embedded and installed:
 - async-foreach
 - gaze
 - get-stdin
 - js-base64
 - sass-graph
 - scss-tokenizer
 - stdout-stream
 - true-case-path

Cheers,
Xavier
