- Moved all common code for part design features view providers to a base
class.
- Move shared code for Sketch based features to newly created
ViewProviderSketchBased class
- Add ViewProviderSketchBased to initialization
- Make Pad and Pocket ViewProviders to use the shared code
- Minor fixes to TaskFeatureParameters and some derived classes
created Partdesign_Hole, Tree_PartDesign_Pad, and
Tree_PartDesign_Revolution SVG icons
Referenced the above in the PartDesign.qrc file
Modified the ViewProviders to display the Tree_icons
for Chamfer, Fillet, Draft, Groove, Hole, LinearPattern,
Mirrored, MultiTransform, PolarTransform, Revolution,
Scaled, Pad and Pocket.
PartDesign_Hole has not been implemented yet however
the ViewProvider has been, so I added the icon
