Undo: update cylinder and weight models on paste

When pasting (or undoing paste) the cylinders or weights may change.
Send the appropriate signals and update the models accordingly.
Currently, this means copying from current dive to displayed dive,
but hopefully we can get rid of "displayed_dive" in the not so
distant future.
