Release Notes
---------------------------------------------------------------------------------------------------------
- Fixed bug that prevented user from stopping an already playing user sound, the same bug also permitted
  a user sound to be started multiple times simultaneously which would not be desired.
- Added an alternate (and optional) idle sound to be played when vehicle is damaged, in the manner of 
  Tamiya (enidle_d.wav)
- Added alternate (and optional) "manual" turret rotation sounds to be played when the vehicle engine is 
  off (turret_m.wav is the repeating portion, optional start and stop sounds are tr_strtm.wav and tr_stopm.wav)
- Added a second light sound to be played automatically when Light 2 (L2 output) is turned on or off via 
  the TCB (see the Sounds tab of OP Config to enable this option).
- Increased the number of user sounds from 6 to 12.
- Changed RC signal handling to allow more flexibility, and made a start on using an INI file to configure 
  settings when used without a TCB in RC mode (not completed).
