a launcher for vscode may actually help compatibility for VScode, giving the correct paths
puting vscode portable vscode in t\vscode seems further experiment to do.

Oganization:

• "vs code.exe" shortcut with a vscode icon
• directory: (see https://code.visualstudio.com/docs/editor/portable )
  • %winpydir%..\t\vscode
    • .\code.exe : the executable
    • .\data : the directory that makes vscode put all its stuff there.
    • .\data\user-data\Use\settings.json : "python.pythonPath": "${env:WINPYDIR\python.exe}", (a tip from https://code.visualstudio.com/docs/python/environments)
