Accidental file delete on mobile.

[Dirk Hohndel]

So this message from Willem (plus some related discussions here and on GitHub, and a suggestion from Peter Zaal) triggered some experiments with some more changes to the mobile UI.
These are making it to the beta streams in both stores as we speak - they should show up as 3.1.3(4.9.10.361) (or newer) soonishly.

These consist of a couple of somewhat separate changes that combined in my opinion give a much better user experience.
But just as with the rest of this, I'm really curious what others are thinking:

- the delete action was removed from the right side of the central action button on the dive details page; the argument that in normal use this is a fairly rare operation and to have it there so prominently was just inviting unintentional dive deletes really made sense to me
- instead delete is now in the context menu, right above (hint, hint) the Undo option
- additionally, the notification messages that pop up after every change and tell the user about our progress storing their data... they weren't really useful to sane people or regular users. So those are gone
- instead we now show a message that summarizes that last change that was saved, and points out that it can be undone, and even offers a button to undo (or redo) things
- that button sneakily doesn't immediately undo/redo, but instead opens the context menu where the user then can decide what they want to do

To me this flow is informative, relatively unobtrusive, and makes sense. Best of all, even if you miss the time window to press the button in the notification, you still can just open the context menu and trigger the undo (or redo) action.

Please, PLEASE test this and let me know how this works for you, if it is intuitive, if this should be changed in some way.
Of course the texts will be translated (and even the command in the button that's part of the notification will be translated).

As of this writing the new versions has just now been pushed for iOS, the Android one is still waiting for Google to review and push out - but lately that hasn't taken too long.

Thanks
