Slicer crash when SLA printer is selected and printer profile is changed
First, there was a bug in the preset Tabs, where a "printer_technology"
was incorrectly queried on "print" and "filament"
(or "sla_print" and "sla_material") profiles.
Second, there was an unsafe "printer_technology" getter, which would add
the missing key to the config container when queried for.
When loading a user provided Config Bundle (not a vendor Config Bundle),
profiles of the same name as the system profiles already loaded into Slic3r
will be ignored, while emiting an error message into the log.
Also when loading a user provided Config Bundle, imported vs. overwritten
profiles are reported into the log as well.
template.
Reworked naming of the plater exports to not use the output file name
template, but to derive the file name from the first printable object's name.
Fixed error handling: Reimpemented the Perl's "eval" blocks
as try / catch blocks.
Removed libslic3r from the default include paths for all modules but
libslic3r. Now headers from libslic3r need to be included with an
explicit path (libslic3r/libslic3r.h etc)
Split the localization macros into I18N.{cpp,h}
