This signal can be used when subclassing SaveDelegate is not
possible or cumbersome. The default implementation of
PanelSaveDelegateClass.save_async() will emit this signal to allow
the consumer to implement asynchronous save in a flexible manner.
The caller is expected to complete task with a boolean when the
save operation has completed.
task
Returns
true if the operation was handled.
