Fix "FileProtection" callback, add InnoSetup

The InnoSetup placeholder here will eventually be a way to call to an external library to extract the contents of the installer, similar to how CAB files are handled right now. The code to o so need sto be converted before that can happen, so in the meantime, this adds Inno Steup itself as a "protection" since other protections could be hidden within.
