This is the first feature that used GeoFeatureGroupExtension and required links to the groups inside as well as to things on the same level. Hence a few modifications to link scopes have been nesseccary.
=============================================================
Prior this commit, if a body has transparency (let's say 55%) and a new feature is added, the transparency is lost until you update it again in the body.
This prevents to actually see through while editing the feature (e.g. while setting the length of a pad) and is very annoying as the user
is required to go back to the body properties, where the old value (e.g. 55%) would still be there and change it to another value (56%) to effect it.
AttachableObjects are desired in multiple occasions, and the current AttachableObject is not flexible enough to handle all cases. Hence the code is portet to an extension, which gives the needed flexibility.
When another bit of information was needed to be extracted from mode
suggestion routine, it felt like listMapModes had too many arguments.
So, the arguments have been collapsed into a struct. This triggered a
few namespace-related changes, which lead to massive search-and-replace
changes all over FreeCAD.
So the only functional change carried out is the addition of reference
types readout to info returned by suggestor.
-Rename Sketchbased to ProfileBased to show new behavior
-Adopt ProfileBased to make the relevant helper functions work with faces too
-Adopt features for unified use of helper functions
-Adopt commands to allow face selection
hasObject does search recursive only in groups, but a body is not a group. Hence for sketches within a body this will always return false. Annother logic must be used to detect sketches in bodies.
