RecentsSettings: welcome to the big kids table

it's a reasonably-large grouping of similar ui-settings. Let's get it away from the UNDESIRABLES in system_ui_more

ps2: Rather than ALWAYS opening omniswitch settings, choosing omni recents now presents the users with
     the same information as it had previously (that omni should be enabled and set to turn on at boot)...
     it NOW offers them a CHOICE to go to omni settings to set/check those settings
