"filament_load_time" and "filament_unload_time" values to match
the MK3 MMU2 behavior.
Emitting of the remaining times into the output G-code was made optional
through a new "remaining_times" configuration value, so the firmware
flavors and versions, which do not know the M73 code, will not complain.
Configuration changes:
The wipe tower default position was shifted inwards after the wipe tower
coordinate reference point was changed from the center to the left front
corner.
Added the "filament_load_time" and "filament_unload_time" values
to the MK3 MMU filament profiles.
Enabled "remaining_times" for the MK2.5, MK3 and MK3MMU2 printers.
based on the Slic3r printer profile.
Also the bundled config has been updated, so that the machine envelope
G-code values were removed and the new Slic3r printer profile values
were updated with the former G-code values.
Slic3r version has been bumped up to 1.41.0-alpha for the configuration
files to work.
Added Version Index "version" method.
Implemented automatic selection of default_print_profile and
default_filament_profile, when the print / filament profiles are
not compatible with the selected printer profile.
Fixed selection of a printer profile, if the currently selected
printer profile becomes invisible.
