adding enable/disable and fill() to PWM usage (Led*) - work in progress
fixed values being set
default fill for ctrl leds is now in config
fixed PWM to work as expected, when connected to p-mosfet on output
removed some garbage from main()
added method for obtaining PWM's frequency (at compile time)
replaced on-bard big fuse with the smaller one (the one that has been actually bought)
Millivolts is now global typedef; draft for the low power handling facility
