---------------------------

* ADD. CAAT.UI.Label now can show images.
* ADD. CAAT.UI.Label now can use <a> anchors.
* FIX. Linear path apply as path was buggy.
* ADD. CAAT.Director.enableResizeEvents now returns this to make it chainable.
* ADD. CAAT.SpriteImage.getWrappedImageWidth and CAAT.SpriteImage.getWrappedImageHeight which returns internal
  image's dimension.
* FIX. CAAT.Actor.cacheAsBitmap could give wrong results.
* CHANGE. CAAT.TextActor now honors font's attributes.
* FIX. CAAT.ShapeActor honors a previous cacheAsBitmap call.
* ADD. CAAT.Actor.moveTo now has a callback parameter which will be invoked on animation end.
* ADD. CAAT.CSS_TEXT_METRICS global variable controls how fontMetrics ascent and descent will be calculated.
  if 0, an estimated 80% of font's height will be used as descent position.
  else, a CSS based calculation will be applied.
* ADD. CAAT.Font.getFontMetrics function which (based of CAAT.CSS_TEXT_METRICS) calculates font information:
  height, ascent and descent.
* CHANGE: CAAT.TextActor now uses alphabetic baseline to position itself in the scene. This fixes FF bug
  where baseline="top" does not give appropriate results. See demo30 fonts.html for a visual test on this.
* FIX. CAAT.currentDirector global variable now always has a value.
* FIX. Scene transitions when using linear paths now fit perfectly.
* FIX. CAAT.LinearPath.applyAsPath now can be used as clip mask.
* FIX. CAAT.LayoutManager.setAnimated now can be chained.
* ADD. CAAT.Label now has shadow, shadowColor and shadowBlur attributes.
