Another release for the LM80C firmware. This one sets improvements in several parts of the code:

• Minor improvements in LIST code:
  • when a line terminates at the right side of the video the code won't send a "carriage return" code anymore (an empty line was inserted, before);
  • printing a list on the serial when the computer is in graphics mode now lets the list to get carriage returns after the end of each line (the list was printed in a row, before).
• Fixed a bug in sound management: automatic cutting down of a tone on a channel wrongly altered the whole sound mixer.
• Added management of noise from PSG: now it is possible to generate noise for each of the 3 channels, mixing the noise with tones, too.
• Fixed some timing issues in VDP access that lead to graphic glitches in graphic mode 2
• Code improvements
