List of the changes in v. 0.9:
* ACC control with 'c' command is fixed. Current ACC state could be saved in EEPROM by 'R' command
* Added support for basic CD Changer control with 'D/d' (disc select) or 'T/t' (Next/prev track) commands. This feature is experimental and not fully tested yet.
* Added support for H70x sleep mode control by 'n' command
* Added support for Master/Slave mode select by 'm' command. Slave mode might be useful to control other Apline digital processors or Amps (i.e. MRA-F350)
* Store settings command renamed from 'T' to 'R'
* Misc. bug fixes
