Addressing open issues.

- Updated jQuery to fix XSS issue in #14.
- Updating `main.js` regex matches to fix JS errors causing #13.
- Updating Makefile for better debugging support through `PRETTY=true make` && `PRETTY=true make server`. `PRETTY` will turn off magnification of css, js and html output.
- Removed IE 6 - 8 support from ba-hashchange, which in turn fixed a javascript error with `$.browser.mise` nully.
- Removed duplication prettify css from doc.less.

This PR closed #13 and #14.
