Title: FlxSprite#overlap and FlxSprite#overlapAt only check the first element of a FlxGroup

It seems the code uses the wrong length variable. The one that is used is always 1, so it will only check the first element of the FlxGroup. This patch uses the length attribute of the FlxGroup object and fixes the behaviour.
