Installer manifest is not currently being used

[psteiwer]

PivotSubscriptions.Installer currently defines an Installer Manifest. However, the readme says to simply call PivotSubscriptions.Installer:RunInstaller(), which does not use the defined manifest.

I believe I remember that the manifest was not working as expected so I decided to use RunInstaller() instead. I do not remember what the issue with the Installer Manifest was so it would be good to review this and see if we can use it now
