Added a separate option for M493 K calibration for Marlin. When I compiled Marlin bugfix-2.1.x I noticed Linear Advance K to be way off from previous calibrated values used with M900 (around 10^-2). The implementation is quick and dirty, divide CurrentValue by 10^3 for the G-code only to get around messing with cura's standard float format. Tested it with 0.1 increments (0.0001 in G-code).
