add: Syntax Plugin, StyleSheet, Canvas Page

1. Syntax Highlight Plugin to work with pygments
2. Updated the default layout to incldue the self-defined stylesheets, jquery plugin, bootstrapJS, together with third-part JS library
3. Using ruby's Favicon.ico. Cuz I like ruby
4. Updated the index page, added a code-moto
5. Added a set of pages to show my work on Canvas API. Added correspondingly:
  - basic.js: basic learning drawing
  - swing.js: intending to do a swing animation; but only managed to achieve a normal simple one. Would update this part in future after I get my math knowledge done.
