Title: Fix a regression with FlxSprite's _maxFrames calculation.

The current approach assumed perfectly filled spritesheets rows. It used ceil() to adjust any floating value, which resulted in a blank column at the right of some graphics.

I've noticed that testing with a game that uses particles. Some particles had that blank column. Removing the ceil (which was Adam's original approach) fixed the problem.
