Release Notes:

Details: Added perf tests that show ~30% speed dimprovement for text,  
LzSprite, LzInputTextSprite and LzTextSprite use CSS where possible,  
clean out old comments from LaszloView, fire sprite.init(true) in  
canvas to show canvas, add style-dhtml.css with default styles,  
updated html-response.xslt to include css and not add redundant  
embednew.js.  Canvas and canvas click mask are now hidded during  
startup, reducing repaints.


Tests: All apps look the same as before in Safari, Firefox 2 mac and  
win, and IE 6.  Startup time is noticably better!
