Draft beziers: Split poles to multiple bezier segments

Draft set degree of bezier curve
Close Draft bezier curves
implement addPoint for piecewise Bezier curves
use circle trackers for control points
prepare functions to make bezier knots tangent or symmetric
make Draft.BezCurve nodes tangent/symmetric
instead of moving both poles to the same side, we make them symmetric

changed icon Draft_BezTanNode
fix DWire,BSpline, BezCurve edit buttons

fix bug in Draft.Edit re incorrect tan/sym on DWire/BSpline
