Improve deprecation message for QLine::angle(QLine)

Browse Source 
angleTo() always gives an answer measured ccw, so between 0 and 360
degrees. The deprecated angle() would give either cw or ccw,
depending on which is smaller, so between 0 and 180 degrees.

Help users porting by showing a simple way to achieve the angle()
behavior in the deprecation message.
