Subject: screen_play: remember playlist
X-Git-Tag: v0.12_alpha1~77
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1d0e05d6b1621a95acdb18ea03d45ce955495ee4;p=ncmpc.git

screen_play: remember playlist

Remove the last paint() dependency on the mpdclient pointer: remember
a pointer to the playlist object, and don't take it from mpdclient
every time we paint.  Also add the variable "current_song_id" which is
calculated in update().
