MIDI: Allow seeking forward and backward using the left/right keys. Currently seeks in 5 second

increments, but this can be set to any amount. Also implemented a counter for playing time, which can 
pretty easily be used to determine the length of the file, in seconds, before playing it. The time 
isn't displayed anywhere right now, but all this can be useful if this thing is turned into a codec, or 
at least gets a nice UI.
