#199 setPageX and setPageY incorrect in IE

[Alexandru Craciun]

In the DynLayer class the functions setPageX and
setPageY for IE set the position as the following:
setX(this.parent.getPageX()-x) respectively
setY(this.parent.getPageY()-y).

Correct is:
setX(x - this.parent.getPageX()) respectively
setY(y - this.parent.getPageY())

Version of DynAPI used: 2.5.6
