Installer Should Not Require Admin

[Breakthrough]

Right now the installer requires admin privileges as it installs DVR-Scan system wide. It should also allow installing only for the current user, which won't require admin. I don't know if the AdvancedInstaller license I have allows customizing this or having a dialog box for it, so should revisit the setup UI to see if it's possible.

[Breakthrough]

This should be possible with the AdvancedInstaller CLI:

AdvancedInstaller.com /edit dist/installer/PySceneDetect.aip -SetProperty InstallationType=PerMachineIfAdmin
AdvancedInstaller.com /edit dist/installer/PySceneDetect.aip -AddDialog InstallTypeDlg -After WelcomeDlg
AdvancedInstaller.com /edit dist/installer/PySceneDetect.aip -AddEnvironmentVariable -Name "PATH" -Value "[APPDIR]" -Component "APPDIR" -Append -InstallAction CreateRemove
