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.

Change loop structure for sample synthesizing. Gives a nice speedup on both coldfire and arm targets.

A loop with one iteration is a little strange, also put it inside an #if block to not rely on gcc otimizing it away

Optimisation of the midi player, reducing the number of multiplications and memory accesses inside a very frequently executed loop, also does shifting of the whole sample when synthing is done which improves accurracy slightly, ~10% fewer buffer misses
