Strip comments and whitespace, and report byte savings.

About this tool
Strips comments and redundant whitespace. It does not rewrite properties, merge selectors or shorten colours — those transformations are where minifiers usually break stylesheets.
Questions
- Is this worth doing alongside gzip?
- Marginally. Compression already handles repeated whitespace well; measure the compressed size before assuming the saving is real.
