as the GCode is generated outside of the Print class.
Exported the GCodePreviewData as GCode::PreviewData to Perl.
When exporting the G-code with a command line Slic3r,
the GCodeAnalyzer is now supressed for performance reasons.
Removed obsolete Perl module Slic3r::GUI::Plater::3DToolpaths.
The PlaceholderParser is currently used by the GCode.cpp
and by Printer.cpp to generate a new name for the exported G-code or SVG file.
The PlaceholderParser::process() will throw a runtime_error with
a comprehensive error message.
The G-code export will include these error messages into the G-code text
with !!!!!! separators, and the GUI will inform the user, that the G-code
export failed.
Removed the Perl dependencies on Encode, Encode::Locale and Unicode::Normalize.
Added dependency on boost::locale.
Added encode_path, decode_path, normalize_utf8 functions to Slic3r.xs
Slic3r.xs has been made mostly utf8 safe by using the boost::nowide library,
thanks to @alexrj for the idea.
Simplified the encode_path / decode_path stuff:
wxWidgets are unicode already, so there is no need to decode_path() from it.
Perl / win32 interfacing is non-unicode, so decode_path() is executed
on ARGV just at the beginning of the perl scripts.

The Prusa3D binary builds are missing the UTF8 libraries.
To avoid having to bundle them, the case sensitive regexes testing
file suffixes were replaced with explicit enumeration of lower / upper
case letters. While crude, it avoids triggering the UTF8 library.
Removed GCode.pm
Removed the Perl bindigns for AvoidCrossingPerimeters, OozePrevention, SpiralVase, Wipe
Changed the std::set of extruder IDs to vector of IDs.
Removed some MSVC compiler warnings, removed obnoxious compiler warnings when compiling the Perl bindings.
When extruding supports, the support is interleaved with interface
if possible (when extruded with the same extruder).
Otherwise the base is extruded first.
inside ClipperUtils are now using bit shifts instead of multiplication
by doubles, which makes the scaling precise.
Removed the scale parameter from all offset functions.
Modified the safety offset to calculate offset per polygon instead
of over all polygons at once. The old way was not safe and very slow,
sometimes this meant a kiss of death for supports for example.
to return a string with an error message instead. This was necessary
to avoid a hang-up on some Strawberry Perl distributions, when
a perl "croak" function is called after a C++ exception is caught.
