Windows file resources can be marked as Private, Special, Debug
and Pre-release. Extend the Heimdal Assembly name to include
designations for these various build options to ensure that
private, special, debug and pre-release builds do not conflict
with the assembly name reserved for public releases. This permits
a private, special, debug and pre-release build to be installed
side-by-side with the final release without interference.
