Minor fixes and improvements

The following has been changed
  - Note::set_param now sets orig-values and does an apply_pfactor()
  - Note::reattack now also reattacks the filter's envelope
  - oscval[i]=0 has been removed as it's unneccessary in Note::get_sample()
  - in Note::get_sample: fm- and out-sums are calculated in 2SCALE now
    and scaled down (via >>SCALE) afterwards (instead of while every
    single add-operation)
  - the filter-envelope is now inited with the shorter constructor
  - todo-list updated

 TODO für den synth
    o notes compilieren und als .so-datei laden
+
+   x BUG: bei Note::set_param sollte statt dem eigentlichen param
+          der orig gesetzt werden und dann neu berechnet werden!
+   x BUG: bei release und reattack: BEIDE male die filter-envelope beachten!
+   o KSL mit powf und floats statt mit double umschreiben
+   o statt lfo-nummer direkten zugriff auf curr_lfo angeben?
+   x oscval-nullen kann in get_sample() weggelassen werden
+   o bei tremolo (und vibrato?): eventuell nicht prüfen, obs aktiviert
+     ist, sondern zur not einfach *1 rechnen?
+   x in get_sample(), beim aufaddieren zum out (und vmtl auch fm-)wert:
+     erst nach dem addieren scalen, statt für jeden faktor einzeln
+             
+   x filter_envelope könnte mit anderem ctor geinitet werden (weniger schreibarbeit)
+   x notes compilieren und als .so-datei laden
+
+   o programme on-the-fly (um)laden
+   
+   x parser-klasse durch parse-funktion ersetzen
+ 
+   x reattack a) garnicht, b) immer, c) nur wenn schon in releasephase
+     --> legatopedal!
+     
+   o bei envelopes: releasephase abschalten (bei sustain bleiben)
+
+   o soft-pedal
  
    o RAM aufräumen?
