Support unquoted attributes

[vzaidman]

if you have svgs with unquoted attributes such as:
xmlns="http://www.w3.org/2000/svg" width=20px height=20px

The error: Error in parsing SVG: Unquoted attribute value is emitted.

I've created a loader to temporary fix this in webpack:
https://www.npmjs.com/package/xml-fix-loader

{
  test: /\.svg$/,
  use: [
    { loader: 'file-loader' },
    { loader: 'svgo-loader' },
    { loader: 'xml-fix-loader' }
  ]
}

Also opened a bug on svgo:
svg/svgo#678

Sounds like an issue with SVGO itself, and should be fixed there. Thank you for creating issue in SVGO repository. This one should be closed I think.
