TreeNode.setIconCls(String) cannot change icon under Firefox after the node has been rendered

  After rendering a node in a tree, it is not possible to change its icon 
under Firefox using setIconCls(String) method. The same code works fine 
under IE. The method changes the value of 'classname' attribute, but 
Firefox likes more 'class' attribute instead :) Thus, a simple patch is 
necessary:

The patch has been tested with GWTExt 2.0.5 and Firefox 3.x
