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

1ba018bb01 Add drum names, make cowbell a default instrument (no way to remap them from UI yet). Add non-static 
wrapper for pressnote (is there a better way?). Beatbox only tested on H300; compile at own risk.

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

93787dd42c Simplify the sendEvent function, makes it _slightly_ faster and quite a bit smaller, build midiplay with -O2 for coldfire, gives about a 23% speedup

memory corruption and other weirdness.

c84461fb8f More adsr related nonsense, argh! Fix adsr related problem on some notes being stopped instead of 
looped. Ramping code still not quite right, but dont want to lose this.

28b5afd05a Optimize synth code by pre-computing the volume scaling for each note. 
Scaling is now calculated once per MIDI event at the most, instead of
once per sample. Increase voice ramping speed, increase number of
active voices a little.

47efba8bbf Fix file descriptor leak that would cause a hard lockup every 7 files 
played. A few other cosmetic changes. please, please no red build =)

b2f1b5dd18 ---------------------------------------------------------------------- 
Added Karl Kurbjun's sound output patch, cleaned up some output.
Main file is now midiplay.c, midi2wav is still in there for anyone who
wants it. Set sampling rate to 22k, and increased note decay time.
Reduced number of concurrent active voices and made new notes replace
used voices if none are available. This makes lag less apparent.
I really hope this wont go red. (turns around and runs)
