physical_printers.
Updated the snapshots dialog to display sla_print and sla_material.
Updated the snapshots dialog to display physical_printer instead of
printer if the physical_printer key is nonempty.
The "physical_printer" key was moved from [extras] to [presets] section
of PrusaSlicer.ini
1) All slicer's exceptions are now derived from Slic3r::Exception.
2) New exceptions are defined for slicing errors.
3) Exceptions are propagated to the Plater to show.
It remains to modify the slicing back-end to throw the new SlicingError
exceptions instead of std::runtime_error and to show the other exceptions
by a message dialog instead of a notification.
Fixes issue with incorrect characters in time strings on UI.
Fix platform dependency
Fix return value with incorrect strings.
Just use strptime and strftime on all platforms.
Emulate strptime on msvc... because they don't have it and their get_time is buggy.
All requested config values are written into SL1 ini file inside the zip
* TIme.hpp and Time.cpp is now part of libslic3r instead of libslic3r_gui
* Updated time manipulation function: separate timestamp_local_str and timestamp_utc_str
* timestamp_utc_str is used in header_slic3r_generated(). Gcode now contains UTC timestamps
A static symbol Slic3r::SEMVER is introduced, which holds
the running slicer's Semver object.
This is mainly done to make testing updater behaviour
_much_ easier. Additionaly to cleanup some questionable code
(Semver was being parsed multiple times / in multiple places
in the frontend.)
