Add Reminder of unsaved changes

[arolfes]

I want to administrate anything. I visit taskana admin

Given I just changed something for a workbasket / classification and forgot to save
When I close the detail view by e.g. switching to a different workbasket / classification (to edit)
Then I expect a popup to show telling me that I still have unsaved changes which I might want to safe before closing the detail view.

Seems like a promising way to do it, however, seems a bit of tedious and large task right now. Atleast when not using extension of components.

Some possible snippets for solution are here
