Improved initializer script for in CodeBehavior.

The current implementation works fine when page loads but when i add new elements dynamically it doesn't work!

Example:
If I switch Tabs in an AjaxTabbedPanel with prettified panels - the other AjaxTabbedPanel will rerender the linenumbers. See screenshot.

Solution:
Initialize with prettyPrintOne() instead of prettyPrint();
