rhbz#1122096 tdf#54834: sw navigator: multi-selection of outline entries

* SwContentTree::ToggleToRoot(): allow multi-selection iff outline root
is displayed
* SwContentTree::ExecCommand(): handle outline operations for multiple
selected entries; since it's not possible to prevent selecting both
parent & child, try to ignore selected children in that case
* add Undo bracketing
* rename misleading "bModifier" variable which was actually true without
the Ctrl key
* regarding SwContentTree::KeyInput(), the KEY_RETURN causes the view to
jump to the entry, and KEY_DELETE is not possible for outline entries,
and KEY_SPACE is only for drawing objects, so no need for handling
multi-selection here
* it probably doesn't make sense to handle multi selection in the
context menu but it appears that the context menu for outline entries
is already quite borked even going back to OOo times
