Desktop: refactor WSInfoDelegate logic

Browse source 
The WSInfoDelegate (weight-system-info delegate) is used to display
a combo box of known weightsystem-types and auto-fills the weight if
the weightsystem-type is changed.

This would overwrite the weight data of the displayed dive when the
user hovers over the different entries. Moreover, it saves the original
weight in case the user cancels the editing action.

This is not viable when implementing undo of weightsystem changes,
because hovering over entries should not produce individual undo
commands. Instead, implement a special "temporary" row in the
weightsystem model. On canceling of the edit actions, simply reload
the weightsystem from the unmodified dive.
