QML UI: keep QML manager and the UI in sync about selected dive

The manager can now directly update the index of the selected dive, and
the UI tells the manager the timestamp of the currently selected dive.
This allows the manager to pick the best possible dive as selected dive
if things change (for example if the dive list gets reloaded because it
changed in cloud storage).

Fixes #1009
