Unwatch events have to remain unfiltered, or the player won't be removed. I now only unwatch the service if it was found in m_watchedPlayersInfo.</p></pre>

So instead, m_watchedPlayersInfo is now checked for a matching serviceName before disconnecting the relevant matching player, if any. This should be acceptable as a workaround, given the very large number of running players theoretically required for it to become prohibitively expensive.</p></pre>

This seems like it'd do the same thing in a much simpler way than monitoring all players all the time?</p></pre>

We now properly account for every player coming and going. This (was) still used when the plugin is activated, and I don't know if it ever actually functioned after a player was removed. If it did detectPlayers() cleared every single player each time a player exited and then slowly rebuilt playback information from playback status updates.</p></pre>
