Fixed Source Map generation when multiple input/output paths are used.

[mkempe]

Hey there,

first of all, many thanks for the plugin.

This pull request fixes the generation of Source Maps when multiple input/output paths are used, for example in an Ember CLI app:

var app = new EmberApp(defaults, {
  outputPaths: {
    app: {
      html: 'index.html',
      css: {
        'foo': '/assets/foo.css',
        'bar': '/assets/bar.css'
      },
      js: '/assets/app.js'
    },

    // ...
  },

  // ...
};

Without the pull request, for /assets/bar.css a Source Map with the name /assets/foo.css.map is created instead of /assets/bar.css.map.

This is probably also the reason for gpoitch/ember-cli-less#32.

Looking forward to this merging.

Previously you were able to pass a sourceMapURL as part of the options.sourceMap hash (line 29 in original file). So I'm slightly confused or misunderstanding the issue. This PR removes the behavior.

Thanks for the PR. Left a question before I can merge, because I think I'm not fully understanding if this is a broccoli-less-single limitation or ember-cli-less. Since it does respect the sourceMapURL option.

Also, please refrain from cosmetic changes. I left it the way the original author intended it, and makes reviews more difficult.

Hey Jason,

many thanks for looking over the PR and your feedback. You are right, with the points you mentioned.
I just looked over the code and identified the "real" problem. The problem is the options handling in line 23: https://github.com/gabrielgrant/broccoli-less-single/blob/master/index.js#L23.

I will close this PR and open another which fixes and explains the problem.

PS: Sorry for the cosmetic noise.
