More Performant

• Fix riot#1511 : Escape Quotes - They may be some issues to fix.
• Regression of logic to parse style and script tags, due to loss of performance and other issues.
• Removed the "compress" option of the less parser, which is deprecated and generates warnings in the console.
• Removed the unuseful CSS parser stylus from the browser version.
• Refactorization of all the code, with more comments in preparation for the automatic documentation of the API.
• Various tweaks to increase performance and reduce (~55%) memory consumption.
• Files to preprocess are moved from "lib" to the "src" directory, now "lib" has the required node.js files only.
