* change mu_util_play a bit to better deal with non-ascii filenames

- don't try to encode anything, but pass the filename into the argv for the
    program to open (before we, used g_spawn_command_line_async, and there we
    need to escape things for the command line. Now we use g_spawn_command, so
    we can pass argv as such.
  - add a GError** arg to mu_util_play, and update all callers
  - cleanup the mu-cmd-extract code a bit
