separate playCount into totalPlayCount and userPlayCount

#96 (reply in thread)

Essentially deprecate playCount for totalPlayCount and userPlayCount. If the servers don't use the same value for playCount might as well work towards removing it with 2 new items

Note that there are scenarios where privacy is important: we don't want a user to be able to deduce anything about other users, such as listening habits.
Therefore, I wouldn't expect every OS server to necessarily implement this field, or if it does, it should be configurable

For a reader not having prior knowledge of these discussions, it's not at all obvious that fields totalCount and userCount have anything to do with the times the song has been played. So maybe they should be totalPlayCount and userPlayCount, even though these require a bit more typing?

I would say that it's up to the server though to handle privacy but a good point. a count doesn't give you much information but it does give you information.

Sure I'll change that now.
