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.
* remove an error message if adding a sketchbased feature without a body
* add champfer or fillet old workflow support
Also rework finishFeature() so at least champfer and fillet may be
inserted into any place of any apropriate body(not only the active one) of the body.
PartDesign: make datum features work outside of body/part
PartDesign old workflow: remove a few messageboxes about no part
PartDesign: old workflow: multitransform without body
Still has visibility issues, but generally works.
Rework combobox filling and link hadling for revolution and transformed features, in order to get rid of hard-coded item indexes and make the lists more dynamic.
They worked and are nice feature, but the handling with properties must be worked out better. To avoid any incompatibility due to property changes the functionality is removed now.
A hole feature is something needed, however, the current implementation does not use the attacher code which would made it intuitive and compatibel to other workbench tools. A reimplementation is needed.
* fix messagebox not popping when clicking OK but status is error
* accept preselection
* unify code for all datum commands
* edit selected datum if type matches, instead of creating new one
* adapt
* introduce mode selection
* kill selection gate to allow selecting whole objects (selection gate
should be reintroduced to disallow references between parts, no
restrictions is a temporary state)
* prevent auto-switchover to next ref after an explicit push of a button
* fix highlighting of buttons when selecting corresponding reference
* allow creation of a feature, even if no mode fits references. With a
warning.
When something was depending on a sketch (another sketch, for example),
padding (revolving, pocketing, etc) it was impossible. This is fixed.
Also, padding or revolving a single sketch twice was allowed (with a
warning msg displayed).
Outside PartDesign sketches can have no support plane for them. But
PartDesign doesn't allow that.
Move the code for migration of "free" sketches of planes
into a separate fuction so it may be reused.
