Stirling-PDF requires reinstallation

[nebulon]

We published the all new Stirling-PDF app with a new appstore package id. The app cannot get updated anymore, since OpenID integration is now only part of the enterprise edition, so it cannot be the default.

This means the current package will not be able to receive any more updates and if you want to keep getting new app versions, you have to reinstall the app from the store. The old package is not listed anymore and the new one is the only one shown in the store.
