You will quickly get a lot of balloons and it is then very tiring to be forced to first select a balloon with a single-click in the drawing, then go to the model tree and there double-click to get the dialog.
This PR also removes unused includes from the dialog code.
as reported here: https://forum.freecadweb.org/viewtopic.php?f=35&t=53664 the balloon text separation no longer works.
The regression was introduced by commit 76357b3fc . The mistake thereby was that the textHeight is already handled before the separators and that rectangular balloons behave differently because of the separator feature.
- in the prefs we call the outline "shape" and this describes it better than "symbol" (it is the shape of the bubble). The line end, however, has a symbol so "Shape" makes clear that is is something different.
