Allow to open file externally by file extension with a specific program

[FloMaetschke]

Issue Type: Feature Request

It would be nice to be able to configure an external editor/viewer/program for specific file types which results in a custom context menu entry and / or default launch behavior on double click.

Example Settings:

"files.extensions": [
    {
        "ext": ".docx",
        "defaultProgram": "C:\Program Files (x86)\Microsoft Office\root\Office16\Winword.exe %filepath%",
        "contextMenus": [
            {
                "title": "Open in Microsoft Word",
                "command": "C:\Program Files (x86)\Microsoft Office\root\Office16\Winword.exe %filepath%"
            },
            {
                "title": "Convert to PDF",
                "command": "C:\mytool\docxToPDF.exe %filepath% %%input:%filename%.pdf"
            }
        ]
    }
]

VS Code version: Code - Insiders 1.21.0-insider (b76a4a7, 2018-03-02T11:59:42.386Z)
OS version: Windows_NT ia32 10.0.16299

VSCode commands should also be considered to be assigned to a user defined context menu maybe?

In my opinion, as I stated in a duplicate not finding this issue, every unsupported filetype should be opened with the default program, unless a keyboardshortcut prevents it.

#50383 was my closed issue, where I mention this in more detail.
