[Development] Deprecation of Qt Quick Controls 1

[Frederik Gladhorn]

Thanks for the feedback :)

Seems like this was a good point to send the mail and we became aware that 
many of you are struggling with the ComboBoxes in Controls 2. Improving that 
makes a lot of sense for us then.

Note that we are not going to make the module magically disappear for the 
moment, it will still be part of Qt releases for the time being.
This was to check what we have left to do to allow a happy transition and 
prepare and nudge everyone else to move to Controls 2.

Cheers,
Frederik
