Summary:  Fix memory leaks in IE 7

Release Notes:

Details: LzSprite.js - More comperhensive destruction of non- 
ie_alphaimageloader images in __destroyImage().  Leave empty hashes  
for LzSprite.prototype.__sprites and LzSprite.prototype._sizedomcache  
in __cleanUpForIE().


Tests: Before this test, reloading any application in IE7 would show  
leakage when hitting reload repeatedly in the browser.  I tested with  
the task manager open to watch memory usage.  This change stabilizes  
image leaks, but there may still be some leaks when data is loaded.
