Better CLI argv file detection

[why-try313]

A simple change in the file detection passed by global.arguments to make sure the file is detected no matter the arguments. I do understand the project is old but still works and does the job

Note: As this includes an old version of electron, it includes the sandbox bug, the .desktop file still needs to be edited and pass the --no-sandbox argument but other than that it's still a program that can easily be integrated on linux

# /usr/share/applications/meshviewer.desktop
Exec="/opt/Mesh Viewer/meshviewer" --no-sandbox %U
