QML UI: do not crash on selecting dive computers

Browse source 
For reasons unknown to me, the DCDeviceData instance was freed way too early,
and used afterwards, obviously resulting in a SIGSEGV. This commit creates
the DCDeviceData as a direct child of the QMLManager instance, ensuring
it does not get freed prematurely.
