feat: Version side by side installation

[bitdisaster]

The PR introduces a new folder structure in the installation folder. That allows updating the App while running without corrupting the state of the installation until a reboot is made. The folder structure will organize the Apps program data into versioned subfolders. That is the same strategy as Squirrel.Windows employs. It will also allow us to introduce the Squirrel auto-updater in a follow-up PR.

C:\Program Files\
└─ MyApp
     └─ app-4.0.0    //Latest or initially installed version
     └─ app-4.1.0    //Updated version
     └─ MyApp.exe //Stub Exe launches the latest version

features:

• App version folder structure is generated automatically
• Semantic versions can be passed in
• Stub-executable is generated with correct file info attributes and icon
• If not icon is provided then the icon of the original home is transferred to the stub (but with reduced quality)

also in this PR

• updated Jest to make Wallaby work
• a small simple demo app is included that allows to run harness
• F5 debugging using the harness script
