make file extensions customizable and/or add .tkapp

[mooreatv]

Can you have a config to say which file extensions should be treated as tcl?

On windows ".tkapp" is to auto start wish.exe so that would be handy

Thanks!

ps: the link https://github.com/bitwisecook/vscode-tcl has no "issues" tab

found how to do it directly in vscode json settings, add:

    "files.associations": {
        "*.tkapp": "tcl"
    },
