mpc play seeks to 0 when already playing

[emeres]

This adds a feature to mpc of using 'mpc play' to restart a song (seek to 0s) when already playing. Patched against mpc version: 0.26 (release-0.25-3-gffcbf13) and tested with Music Player Daemon 0.19~git (release-0.18.9-941-g74a05a7). Struct put before first 'if', should make the second one unnecessary.
