This is a lot of changes in a lot of code because nothing here was abstracted into the sound system. :(
Hopefully most of the affected code here can be tossed out soon, it's not pretty.
- Added names for system RX/TX channels
- Detect if map requires new features to work properly via special TX and command
- Effect Gen update
