This commit seeks to improve the paltry help menu item. It breaks the "try to have at least three items in a submenu" rule in anticipation of an upcoming quickstart guide and show quickstart guide setting. This guide will explain that (soon) you will have to swipe south at the top of the screen to activate the menu.
Also see the somewhat related #1371, which would also go in the submenu.
While looking into #1219 I accidentally ended up refactoring some stuff.
Tested in emulator and on H2O, but be wary because I might have overlooked something.
