Flowrate Adjustment on main screen

[AnHardt]

I do have the Large graphical display. When I go to the ultralcd.cpp and look for the "feedrate_multiplier" to replace, it isn't there. There are a lot of "feedmultiply" called out.

Yes. 'feedmultiply' for the older versions (1.0.2 and before).
But in that case also 'extrudemultiply' instead of 'extruder_multiplier[active_extruder]'
