OmniGears: Fix issue with Settings/Buttons and recents H/W key

- When disabling hardware keys and enabling navbar, if you go and try to enable custom actions,
you will notice that the app switcher is enabled unlike the other keys.

I know this isn't ideal because if you disable the h/w keys, why in the world would you go and
enable custom actions but if for some reason someone does this........this fixes that :-)

PS2 - Added the same precaution for Search key (untested but should work the same)
