laser enable/disable pin not used #1

M3, M4, M5 sets gc.laser_enable but nothing happens with this variable. Also on laser_init the laser is disabled, meaning the bin is not grounded (need to double check). See laser_contol.c

WORK AROUND is to simple wire the enable/disable wire to ground.

the init code now sets the dis pin low. The laser is always enabled but the pwm duty cycle is set to 0 accordingly. Not sure we need the dis pin.
