Subject: introduced statusobject to app.js, file get reqeust parameter now
 gets handled within app.js and not in viewer.js anymore. fixed a bug where a
 placed signature would dissappear if the user scrolls too far away. updated
 some stylesheets. parent and child frame dont talk via postmessage anymore,
 instead functionality of the DOM is used. added porject report /
 documentation
