[2/2] Add option to change size of QS ribbon bar

PS2: Use narrow for 2nd size and decrease margins for smaller tiles
PS3: Remove trailing WS + rebase
PS4: Rebase and fix unchanged dimen use
PS5: Fix renamed dimen missing
PS6: Change narrow to automatic and move applying of settings down
PS7: Make small be narrow instead. "Small" is actually Auto (Narrow)
PS8: Use measuredWidth and modify HorScrollView, otherwise layout changes will be ignored
     (Orientation switches were a big problem)
