Remove namespaces (resolves issue #1238) and use createElementNS even in IE when possible (these nodes are temprary and never actually go into the DOM, so no need to trigger MathPlayer).  I don't know if the m: is right for earlier IE, since element.nodeName may return that and cause the same problems as 1238.  That should be checked.
