Move frame settings to the global section

global section to be consistent.

 ### Changed
 - Text and icons are now centred vertically
 - Notifications aren't considered duplicate if urgency or icons differ
+- The frame width and color settings were moved to the global section as frame\_width and frame\_color respectively.
 
 ### Deprecated
