Berthold Stoeger 63414fc823 undo: show multiple dive warning when editing equipment
When editing cylinders or weights directly in the table widgets,
no warning was shown if multiple dives were affected. To solve this,
emit signals from the respective models and catch them in dive
equipment tab. Not very nice, but it works for now.
