Add a Warning icon on the changed tabs, for edition of dives.

Adds a Warning icon on the changed tabs, this is important as
usability, for you could change something on the 'notes' tab,
change the tab and did't realized that something was changed
( by forgotting or something ), then clicking on the cancel
button. so now there's a friendly reminder that you actually
changed something.
