More updates on iOS...

If I run Subsurface-mobile under the debugger from within Qt Creator, it
does create the drop downs correctly. But if I run it from Xcode (or build
an ipa with Xcode - which is the only way I can create an iTunes package),
then the drop down is non-functional.

Worse, when I then try to download data from a BLE dive computer, the app
just hangs. I can't make sense out of what I see in the debugger when
stopping the app and looking at the different threads. Every thread seems
to just be sitting at a semaphore. And it seems that I no longer get debug
information as at least one of them is sitting and hanging with the stack
indicating that this is in the middle of trying to print out a qDebug()
statement.
