Extended ConfigBase with set() functions similar to the upstream Slic3r.
ConfigBase::set_deserialize() newly throws if the operation fails.
Extrusion width parameters are newly tested for negative values.
DynamicPrintConfig::full_print_config()
new cheaper constructors of DynamicConfig / DynamicPrintConfig from ConfigBase
Unit tests: ported test_model from upstream Slic3r, thanks @lordofhyphens
Unit tests refactored to use less autos and initializer lists for readibility,
DynamicPrintConfig is handled by value, not by shared pointer.
If the custom toolchange gcode switches extruder to the one that is expected, PrusaSlicer does not issue its own T command
Otherwise, this command is inserted just after the custom gcode, even in case it is not empty
This should prevent issues such as #2884 and #2886 from being reported
Since the value inserted from the keyboard or clipboard is not updated under OSX,
we forcibly set the input value for SpinControl every time during editing.
Thus we can't set min control value bigger then 0.
Otherwise, it couldn't be possible to input from keyboard value less then min_val.
Integration of the "cereal" serialization library.
Serialization / deserialization of the DynamicConfig / DynamicPrintConfig.
DynamicPrintConfig serializes ordinal identifiers instead
of the option key strings to conserve space.
for FDM, and "[input_filename_base].sl1" for the SLA technology.
This improves the situation of
"Filename creation with variables broken"
https://github.com/prusa3d/PrusaSlicer/issues/1918
where anything after the last dot in the file name is considered
as an extension, therefore the .gcode resp. .sl1 extension is not added.
Now the user gets the output_filename_format filled in with the correct
extension.
Also now if the output_filename_format is empty, the output name
is generated anyway.
