HTML minifier

Minimize is a HTML minifier based on the node-htmlparser. This depedency will ensure output is solid and correct. Minimize is focussed on HTML5 and will not support older HTML drafts. It is not worth the effort and the web should move forward. Currently, HTML minifier is only usuable server side. Client side minification will be added in a future release.
