hotkeys: Handle up/down arrows in settings page.

Browse Source 
The up/down arrows now navigate the left pane of the settings menu.
The code here was originally implemented as part of our settings
redesign, but the code was added in a place that became unreachable
after we fixed a bug with home_tab_obscured().  This commit
resurrects the code and places the guts of it in settings.js.  It
is possible that we want to clean this code up eventually to deal
better with hidden blocks.
