- Since realthunder's contributions some months ago, the 4 pattern features (mirror, linear, polar, mulitransform) can handle several features at once.
This PR allows to select multiple features when creating a pattern.
(This speeds up the workflow because at the moment one has to create the pattern with one feature and subsequently add more.)
- fix dialog issue that Add and Remove button could be active the same time
- use the keyboardTracking feature to avoid unnecessary recomputes (e.g. currently 3 recomputes when inserting "12.5" to the length field of linear pattern)
- fix wrong <extends> statement in .ui files (automatically spotted and fixed by Qt's Designer)

+ fix memory leak by using QDialog on the stack
+ open a transaction where needed when making a copy to avoid mess with undo/redo
+ set proper title and use main window as parent
+ replace class name Dialog with PartDesignGui::DlgReference
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.
