Subject: - Extrudmultiply with code M221 Sxxx (S100 original Extrude value) -
 use Feedratefaktor only when Extruded lenght > 0 - M106 / M107 can drive the
 FAN with PWM + Port check for not using Timer 1 - New Option -->
 FAN_SOFT_PWM, with this option the FAN PWM can use every digital I/O (PWM
 with 500 hz) - Added M93 command. Sends current steps for all axis.
