Summary: Inline LzCSSStyle._selectorApplies() testing and first level  
of recursion

Release Notes:

Details: Do early tests to short-circuit calls to _selectorApplies 
().  Change structure of _selectorApplies() to set a result variable  
and break rather than retunring immediately.  Inline first level of  
recursion (ugly, but it gets the most results).


Tests: Silver main.lzx?lzr=dhtml&lzt=html shows a total of 56350  
fewer function calls in firebug (from 307750 to 251400).  Calls to  
_selectorApplies() have been reduced from 125068 to 66294 calls.
