The use of Unix domain socket has performance and security benefits.
This adds Scala syntax for VS Code. The current plugin was relying on daltonjorge/vscode-scala for detecting that `*.scala` is a Scala source. This change integrates the plugin into this one.
daltonjorge/vscode-scala is licensed under MIT license.
