Seeking and positions

Use the mmr_seek() function to seek to a known position in a track or a track in a playlist. The position is a string in the format "99:9999", for example "2:1200", where the first number is the position in the current playlist, and the second is the number of milliseconds from the beginning of the specified track. If the current context input is a track, simply specify the track position in milliseconds, for example "1200".
