Extend pluginOptions to also cover gulp-sourcemaps

[narthollis]

As per issue #64

Currently this both the options for sourcemap.init and sourcemap.write compressed into the same option.

I can't see any option conflicts upstream, so I don't think this would be an issue.

Thanks for the PR! Definitely on the right track. A couple things:

• There does seem to be one overlap in init/write options: debug. I'm not entirely sure if people use it for init and not write or visa versa, however to be more explicit about this I think we should support each individually, e.g.:

main: {
  scripts: [
    './*.js'
  ],
  styles: [
    './*.css'
  ],
  options: {
    pluginOptions: {
      'gulp-sourcemaps': {
        init: {loadMaps: false, debug: true},
        write: {addComment: false},
        destPath: '../maps' // this is the string "maps" by default
      }
    }
  }
}

• Also, I could see people needing to supply different options to scripts vs styles. In order to support this we would structure it how we structure other options, but in this case use defaults in case you want to do the same for both streams, e.g.:

main: {
  scripts: [
    './*.js'
  ],
  styles: [
    './*.css'
  ],
  options: {
    pluginOptions: {
      'gulp-sourcemaps': {
        init: {debug: true},
        write: {addComment: false},
        destPath: '../maps',
        scripts: {
            init: {loadMaps: false},
            write: {addComment: true} // overrides {addComment: false}
        },
        styles: {
            init: {loadMaps: true},
            destPath: 'maps' // overrides '../maps'
        }
      }
    }
  }
}

Let me know if you'll be able to look into these items or have different ideas

[narthollis]

Yeah, this seams all quite reasonable.

I will get this sorted tonight and update the PR.

[narthollis]

I have updated this pull request with the suggested chnages.

[chmontgomery]

I assume you mean sourcemapBaseOpts here instead of sourcemapDefaults?

[narthollis]

Yeah, i thought i had fixed that typo sorry. I had fixed that one localy.

[chmontgomery]
