From a Windows desktop to a Linux host has incorrect directory slashes

[deanhouseholder]

When your VS Code is running on a Windows desktop, and you're connecting to a Linux host it fails to explore files and uploaded files have backslashes. So it creates a new directory on the linux host in the format of:
/home/user/code/project1\directory1\file1

This is obviously invalid so it doesn't save into the code project but instead creates:
project1\directory1
project1\directory1\file1

Slashes need to be reversed depending on target OS.
