2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

cd963d84ca 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.

f619f81676 Change loop structure for sample synthesizing. Gives a nice speedup on both coldfire and arm targets.

5118f48d73 A loop with one iteration is a little strange, also put it inside an #if block to not rely on gcc otimizing it away

e1940b87b0 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

6888db3240 Do not duplicate const table, make getEvent function static inline, gives about a ~1.5% speedup, put tick function in iram, ~3.5% speedup
