Sigh tries to load gulp plugins which is not defined in sigh file

[unlight]

I get error when running sigh, from gulp-tslint. I have gulp-tslint in devDependencies, but I do not have tslint var in sigh.js. Why sigh tries to load it, if it will not be used.

var merge, glob, concat, write, env, debounce, pipeline;
var ts;
var ava;
var thru;

module.exports = function (pipelines) {
// ...
};

ATM it tries to inject every gulp plugin, maybe I can use rewire to check which are defined.

Yeah this can be fixed pretty easily. I'm busy for a week or so, I can point you in the direction of the fix if you feel like opening a PR, otherwise I'll get to it in a week or two.
