New rayCastTo() python method for KX_GameObject:

rayCastTo(other,dist,prop)

Look towards another point/KX_GameObject and return first object hit within dist with a property that match prop, None if no object found or if it does not match prop.

Parameters:
  other = 3-tuple (xyz coordinates) or object reference (target=center of object)
          (type = list [x,y,z] or object reference)
  dist = max distance of detection (can be negative => look behind)
         If 0 or omitted => detect up to other
	 (type=float)
  prop = property name that object must have
         If empty or omitted => detect any object
         (type=string)
