Exclude setting doesn't work

[mark-wiemer]

The extension opens all AHK files in the workspace to determine what AHK version to use and update their icon accordingly. However, this interferes with the exclude logic of the new language server, as it reads any file that's opened, regardless of why the file was opened.
