Since the whole thing with Android going full screen with margins, the
combobox popup idea started showing a big flaw; Qt no longer clips the
window on top to the content area and thus your top and bottom item may
become impossible to select.
This replaces the combobox with a new component; a thumbler. Based on
the extremely basic one from QQComponents we introduce our own and use
that to select the year and month in the import screen.
This upgrades to the latest stable Qt (6.8.3) to my surprise the
translator patch still is required and they didn't fix that bug
for 2 bugfix releases now.
This reverts a broken Qt patch wrt translation selection. See QTBUG-131894
This removes various Qt features from the build that we don't need
in order to keep the library size down.
The qtdeclarative module went from 4285 ninja tasks to 2387, or for the
android buld from 4117 to 2251.
