Release Notes:

Details: LzNode.lzs - Move test for __LZstyleConstraints outside  
__LZapplyStyleConstraints() to save method calls.  Avoid checking  
dep.length twice in applyConstraint().

LzCSSStyle.js - Inline _compoundSelectorApplies() call in  
getPropertyValueFor().  Simplify/rename _selectorApplies()  
_compoundSelectorApplies() as it now only applies to compound selectors.

LzSprite.as - Avoid sending resource load events for empty resources.

Tests: http://localhost:8080/wafflecone/...silver/main.lzx? 
lzr=dhtml&lzt=html shows ~37152 fewer total method calls (from 206356  
to 169204).  At least 44288 calls to _compoundSelectorApplies() have  
been eliminated.  http://localhost:8080/wafflecone/test/smoke/ 
smokecheck.lzx passes.
