CSSO, CSS Optimizer plugin for Metalsmith

New in 1.x

• Updated to CSSO version 3.5.0
• Updated to Metalsmith version 2.3.0
• Changed testing framework to tape
• Refactored tests to use temp directory for output to avoid flaky tests

Restructuring

To block CSSO from optimizing the structure of your CSS use the option restructure: false (default: true).

Source maps

Added rudimentary support for the CSSO option sourceMap: true (default: false) to generate corresponding source map files for each CSS file.

CSSO (CSS Optimizer) is a CSS minimizer unlike others. In addition to usual minification techniques it can perform structural optimization of CSS files, resulting in smaller file size compared to other minifiers.
