[RAPPS] Automatically generate installer/uninstaller for downloaded zip/cab files (#6652)

Browse source 
With a single database line added to applications distributed as zip/cab allows rapps.exe to act as an installer that automatically extracts the files and creates a startmenu shortcut. It can also uninstall the extracted files (and optionally other files and registry entries created by the application).
