OrcaSlicer/src/libslic3r/GCodeWriter.cpp
Lukas Matena 8c89bf748b Implemented new acceleration control behaviour for the new Marlin firmware flavor: 
- show extra travel acceleration settings in 'Machine limits' page in Printer Settings
    when the new firmware flavor is selected

- updated tooltips on the config values (they were basically wrong even in the current version)

- 'Marlin (legacy)' firmware flavor behaviour should not change: it exports M204 Pa Rb Ta
    (where a, b are the values from machine limits) at the beginning of gcode and it uses
    M204 S... for feature type dependent acceleration settings (legacy variant of M204 P.. T..)

- new Marlin Firmware exports M204 Pa Rb Tc (where a,b,c are the values from machine limits).
    Feature type dependent acceleration is set using M204 P..., not overriding the travel acceleration.
