Fixed RU translation and date format

I fixed two things:
1. Russian translation for "saved" case.
2. Time/date format for listview. With old format an admin can't see the difference between 11:00:00 time and 23:00:00 time (or 11:00 AM and 11:00 PM). I fixed it for russian locale so you can reject this part of the pull request and do it in another manner.
