Linux support

[Velociraptor45]

Hey @garyhuntddn,

building upon your work, I've now implemented the following things:

• Ensured correct line endings for shell scripts
• Ensured that node_module binaries can be executed on Linux
• Fixed the build.sh script to correctly package node_modules
• Handled Linux file path issues (directory separator & file capitalization)
• Added a pipeline for
  • .net Core on Ubuntu
  • .net framework on Windows
  • .net Core on Windows
• Commented out the Scss unit tests that are already failing in the base repo (see here) in order to get the pipeline green
• Fixed all other unit tests
• Fixed rebuild of the whole WebCompiler folder in the temp directory on each compiler execution

Let's maybe squash the commits once you're ok with the changes. I needed a lot of debug commits as the Ubuntu pipeline is behaving quite different from the WSL-Ubuntu.

Hey @garyhuntddn, do you have any estimation for when you have time to look at this? :)
We might have to still tweak one or two things in the shell scripts
