Specs for techMap

[qfox]

E.g. we need to freeze in specs what techMap should do with multiple extensions:

techMap: {
  image: ['jpg', 'png', 'svg']
}
// should return all the files or just the first one or anything else?

[tadatuta]

Sure it should return all of them (e.g. for vanilla.js and browser.js and js) and then gulp-one-of can filter the first matched if needed (e.g. for post.css or css).
