profile: remove AbstractProfilePolygonItem::settingsChanged()

settingsChanged() is a virtual function, which is called
when the preferences dialog signals changes. In most derived
classes, the function does nothing.

In two classes, DiveProfileItem and DiveCalculatedTissue, it
replots the item respectively changes its visibility.

However, these two flags are *not* controlled by the preferences
dialog. Indeed, the functions are also connected to finer-grained
qPref signals. Therefore, settingsChanged() can be removed.
