The problem was caused by the gap fill algorithm, which worked
with square extrusion width values as with rounded extrusion widths,
which sometimes lead to negative extrusion cross sections
for high height to width ratios.
The extrusion width logic has been changed to consider the input width
to be the extrusion spacing, not the extrusion width. The change certainly
removed the negative feed rates, but it also certainly increased the gap
fill width to some exent. It needs to be verified now, whether the gap fill
does not extrude too much.

The previous way of checking that _putenv_s is defined does not work,
because _putenv_s is a function and not a define. This is a partial
application of commit 31115e0369747b1e1c45cbe3f2a90f6dff66666a from
alexrj/Slic3r.
I tried cherry picking the whole commit, but unicode is already handled
diffrently here, so that would have been a lot of work.
due to the differences in the M203 code
(RepRap firmware has it in mm/min, Marlin in mm/sec).
This difference is important to the G-code time estimator.
Changed the g-code flavor to Marlin for all Prusa3D bundled profiles.

The "Send to OctoPrint" function will now send the file name encoded
in UTF-8, so the file name will not get mangled.
The C++ Slic3r::encode_path() function was returning a string to Perl,
which was marked as UTF-8. This has been fixed, now encode_path() returns
a plain Perl string.
Added path_to_filename, path_to_stem, path_to_extension, path_to_parent_path
Perl wrappers to boost::filesystem::path splitting functionality
to be able to split UTF-8 encoded files on Windows correctly.
the compatible_printers list is non empty.
Changed the precendence of compatible_printers_condition over
compatible_printers. Now compatible_printers has precedence.
wizard if the wizard is opened from the menu. This allows one
to reinstall the bundled printer profile cleanly.
Fixed a bug when loading a config bundle as a config: The config bundle
should not be unpacked into the user profile directory.
