Add-in system

I’d like InnoSetup to have an officially supported add-in system, that loads add-ins dynamically from disk that are not present at the time of compile, and may or may not be present at runtime.

• Add-ins are some kind of file archive (zip, etc.)

• The iss file doesn’t have to know about the add-ins, their filenames, or how many add-ins there are (but the filenames could follow a specific naming convention, such as myProjectAddin-*.zip).

• UI shows what add-ins are available and you can select which to install (ideally with a pretty name, not the filename of the add-in)

• UI shows the size of the addin, this works in a similar manner as components

• Installer knows what add-ins were installed and can support uninstalling

• Add-ins can be digitally signed
