PWM and PPM can now coexist in the same load and be selected at boot time via the hwsettings UAVObject. This is basically a complete restructuring of the way the drivers interact with the TIM peripheral in the STM32. As a side effect, the PWM and PPM drivers are now ready to support multiple instances of each. This also provides the first step toward being able to reassign some of the PWM input pins to be servo output pins. Still more work required, but this is a good start.
