* support for internet explorer 7 & 8
  * redirect by setting window.location.href loses referrer - use fake link
  * implementing position:fixed for status bar in java script
  * when visibility=inherit, go up the dom to find out whether an element is visible
  * avoid .data() completely in followingpages.js
  * some specific html and css
 * adding v parameter to loaded script to invalidate caches
 * regenerating piwik.js (i hope it worked properly this time)
 * hiding notifications that get stuck after removing a hovered element (only happens sometimes)
 * binding window.resize after every broadcast.pageload() - the binding was lost after opening a popover
 * fixing mode with frames disabled: didn't work after migration to the l parameter

This version is the first one that I think is stable. Please deploy on the demo so we can do some more testing.

The next step is translation and documentation. After that, we're ready to release as beta.
