See #256 for more info.

Usage:

bb.init({
   screen: {
       bounce: false,
       onScrollMove: function(e) {
           // Handle scroll move
       },
       // and more ...
   }
});

Can you also apply the changes to the bbui-0.9.4.js in the samples directory

Also, could you possibly list all the properties that are supported to pass in with the screen property. It will help me document it on the wiki :o)

In my opinion the 'scroll-panel' needs this settings too.
