Minor borders to Settings

Doing it the easy way here, where this would effect all the items but since the radius is minor
it shouldn't become separated. Hoping this works, if it doesn't I will just create 2 layouts
for top and bottom list items and then add radius to only those items lol - thats a much
more dirtier and harder way. SO Android, let this work fine :D lol
