Small bug when using NoArrow and title = Nil

[Janne-M]

In FPPopoverView, -(void)setupViews, the contentRect calculation is wrong when arrorDirection is NoArrow combined with no title.

contentRect.origin = CGPointMake(10, 30); contentRect.size = CGSizeMake(self.bounds.size.width-20, self.bounds.size.height-40);

Should be: contentRect.origin = CGPointMake(10, 10); contentRect.size = CGSizeMake(self.bounds.size.width-20, self.bounds.size.height-20);
