allow a page to have a data-template and improve xing/hash to have better parsing of page hashes (allow slashes).
Multiple Updates (see list below)
  * Upgrade Code-bases
    * jQuery 1.10 to 1.11
    * Bootstrap 3.0.3 to 3.1.0
    * Zepto 1.0-1 to 1.1.2
  * Add xing/session and add JSON fallback (using json3 in lib/json)
  * Add xing/http
  * Add src/ folder (separated jquery-combined.js and zepto-combined.js)
  * OPTIMIZATION: zepto|jquery-combined files contain jquery or zepto combined with bootstrap so only one http request is needed
  * change .page tags to .page.row and remove .page definition in style.css
  * put a .container outside of pages and remove redundant .container/.rows from other content.
