player: deal with some corner cases with playlist navigation
The purpose is making accessing the current playlist entry saner when commands are executed during initialization, termination, or after playlist navigation commands. For example, the "playlist_remove current" command will invalidate playlist->current - but some things still access the playlist entry even on uninit. Until now, checking stop_play implicitly took care of it, so it worked, but it was still messy. Introduce the mpctx->playing field, which points to the current playlist entry, even if the entry was removed and/or the playlist's current entry was moved (e.g. due to playlist navigation).
