Fixed existing counters showing 0 on the screen

For any user that had existing counters (such as anyone who had savedata from before the time that Maelstrom, Lacerate, and Sunder were converted to custom counters automatically) in numeric mode, a 0 or faded graphical icon was showing up all the time after the recent change to enable showing empty counters. Now there's a checkbox for whether you want the empty/0 count to show or not.
