move variable to proper location
Created Xgate channel config to allow users to easily specify which xgate channel
they want an output on. Currently there are 24 channels availiable(0-23, portB-portD).
This gives you a total of 30 configurable outputs, 24 BB on fuel and 6 on the hardware
timers.
Remove misleading ON word describing the event structures
added TODO to improve xgate pin configuration from the s12 core
Add additional config to specify which xgate channels are to be used.
