Summary: Add support for CSS3 transition attribute

New Features: Node attributes that have corresponding transition set will be automatically animated.  See LzNode.transition for more details.

Bugs Fixed: LPP-9020 - Support CSS3 transitions

Technical Reviewer: ptw
QA Reviewer: hminsky

Release Notes: Setting the 'transition' attribute will cause subsequent calls to be animated, e.g.:

<canvas> 
    <button transition="x 2s" onclick="this.setAttribute('x', 200)">Hello Laszlo!</button>
</canvas>

Details: LzNode - Add transition propery event and setter that parses the CSS3 transition syntax.  Override LzEventable.__skipSetter() to do transition animations.  

LzEventable - Add __LZskipsetter hash to track attributes that should have their setter call skipped and __skipSetter() called instead.  

LaszloAnimation - Inline setValue() calls into update().

Tests: Animators run as before clicking this button causes it to animate:
<canvas>
    <button transition="x 2s" onclick="this.setAttribute('x', 200)">Hello
    Laszlo!</button>
</canvas>
