Fix multiple typos in QLineF documentation.

QLineF::angleTo, QLineF::setLength(), QLineF::dx() and QLineF::dy()
were missing detailed information

QLineF::angleTo - method returns the angle of two lines compared to
each other. Documentation stated that the return value is in degrees.
This fix adds specific information that the return value (angle)
is returned in _positive_ degrees. setLength()-method missed
information whether the angle is also changed if the given length
is negative. Added mention that angle is also changed. dx() and dy()
didn't mention whether the return value is negative or positive.
Added mention that positive if p2()>=p1() else negative.
