The 3 icons at the top of the account screen now have 2 with actual
icons. They don't look very good, but at least its better than no
icons.
Also I stole most of the receive screen from desktop and ported it here.
Quick and dirty as that screen has been long overdue for a refresh.
We now hardcode the style and I needed to override the Label
in order to explicitly use the palette from the mainWindow. Not
sure why the one on Android behaved different than on Linux.
On the mainscreen have some big tab-buttons for the main features
then we have a menu overlay which can hold various other screens
and features. Those screens will be placed on top of the main
tabbed screen using a stack-view which is common on touch-interfaces.
