commit 8a810680960f0e7d2d9e10b6f21da21332a5bbfe
Author: Philip Withnall <philip tecnocode co uk>

Use the new totem_playlist_add_mrls() API to add multiple playlist entries
As described in the previous commit, this new API ensures that when adding
multiple playlist entries asynchronously, they're not added to Totem's
playlist out of order. Closes: bgo#636686
