Fixed Speed, Distance and Drawing Angle sensors

This patch makes the following user-visible changes:

1) Speed and Distance sensors are fixed
2) Drawing Angle sensor became much more stable and smooth
3) Drawing Angle sensor works right on the rotated canvas

Technical details:

This patch hugely refactors the distance information part of
our painting system. The two most significant changes:

1) KisPaintInformation doesn't have movement() method, because it
   used to get inconsistent *very* fast when the lien was split into
   chunks in paintBezierCurve. The access to drawingDistance(),
   drawingAngle() and drawingSpeep() parameters is provided only by means
   of teh associated KisDistanceInformation.

2) (follows from the point 1) From now on paintAt() function also accepts
    KisDistanceInformation object, because otherwise it will not be able
    to access the calculated parameters.
