Config tool generates deprecated command

[nikscha]

The (old) config tool generates the deprecated M568 "enable mixing" command when enabling mixxing extruders:

; Tools
M563 P0 D0:1 H1 F0                              ; define tool 0
G10 P0 X0 Y0 Z0                                 ; set tool 0 axis offsets
G10 P0 R0 S0                                    ; set initial tool 0 active and standby temperatures to 0C
M568 P0 S1                                      ; enable mixing for tool 0
M567 P0 E0.5:0.5                                ; set mixing ratios for tool 0 

This results in setting the active temperature to 1C at startup.

This doesn't happen with the new config tool, but there's also no option to set the mixxing ratio
