With these changes, one face per solid can be added as either the first
"profile" or subsequent sections in loft and pipe.
This commit depends on `App::PropertyXLinkSubList` preserving the order in which
sections are added.
A minor change this also adds is that when a solid's face is selected that face
is mentioned in the fields instead of the solid (eg `Box:Face1` instead of
`Box`).
- Rebase App::Origin on App::DocumentObject
- Keep all control over the Origin structure inside the Origin and it's
ViewProvider
- Add OriginFeature class as common base for App::Plane and App::Line
- Rebase App::Plane and App::Line on top of newly created class and
move to the file.
- Change Origin's ViewProvider API associated with temporary display
- Lots of associated changes to files
- Several minor fixes
- Lots of new bugs
Added a new class: TaskDlgFeatureBased which currently contains common
code for TaskDlgSketcherBasedParameters::reject() as well as the same
methode for TaskDlgDressUpParameters.
It's likely that other Feature task dialogs will inherit this class too.
