PrusaSlicer-NonPlainar/src/libslic3r/utils.cpp
Vojtech Bubnik 01406fd521 Worked around some quirky Linux file system issues. Namely 
the Chromebooks share their file system to Linux using the 9p file
system, which does not support setting file ownership. Newly PrusaSlicer
will detect platform and it will not panick if copy_file() cannot set
file ownership after copying. It just logs the incident, and on
chromebooks the loglevel for that incident is "Info", not "Error".

Adjusted the full screen mode to contain menu bar.
Moved Platform.cpp/hpp to libslic3r
