[Pkg-javascript-devel] Bug#961111: add an option to specify build-only components in watch

[Yadd]

Hi,

pkg-js-tools permits to choose components to install:
  * by listing components to install in
    debian/nodejs/submodules
  * or by adding "!componentName" in
    debian/nodejs/additional_components

Then a component listed in debian/watch could be used for build only.

Cheers,
Yadd
