Start porting User page to QML2
dialog to pick a user avatar in QML

work in progress
better canvas text layout
save/remove the user avatar

also correctly reflect the new avatar on the push button upon saving
fix getting user properties

also prefer AccountService
allow to select a custom user picture

the QML file dialog doesn't seem to work ATM tho :/
preset the known location

and stop the busy indicator after 5 seconds,
it shouldn't loop forever thus denying the user to enter the location
manually
trim the location string
use the standard kdm faces dir
drop the old widget based face dlg
finish UserPage cleanup
