Torbjörn Andersson 711f925f69 Always play the "current music" after restoring a savegame, even if it's 0.
If it is, all that happens is that it silences the music. Otherwise, the
current music that was playing before the game was restored will keep
playing afterwards.

(One example of this: I went into the Hotel Ubu and restored a savegame at
the hospital. The piano music kept playing in the background.)
