Some suggestions for improvements

[DanielRuf]

• Add the jquery.js files and the persona login file in the repo
• use a newer version of jQuery (1.9.1) as file
• replace some PHP code with jQuery
• replace session vars using solutions like cookie.js
• autoupdating contents using smartupdater
• use JSON where possible - as database? maybe with TaffyDB.js (stores it also in localstorage)
• update Twitter Bootstrap
• maybe add some typeplate elements
