Subject: [PATCH] QML UI: handle editing of depth

Getting closer to being able to really edit / add dives in the mobile UI.
This works for manually added dives - needs a bit more thought for dives
downloaded from dive computers as we don't necessarily want to change the
maxdepth in conflict with the samples.
