When building for wx3 on Linux, the backported number validators and formatter conflicts with the wx3 version because I never renamed them. Crashes during termination would occur because the wx3 version and our version had different vtables. I was thinking that we would just be able to delete the backported version when upgrading to wx3, but since we've made Audacity specific changes to them we can't simply start using the real wx3 versions anymore. Therefore, I needed to rename then to prevent the crashes.
