/* Function: AddStartupIssues
*

* <StartupIssues> rather than replacing them, which means flags can be set but they cannot be cleared. More than one can
* be set in a single call so you can pass a combination of flags. If any of them weren't previously set it will notify the
* <IStartupWatchers> of the changes.
*
* You can pass one startup watcher to not be notified, which can be used to prevent a module from receiving its own notification.
* If that notification leads to other startup issues being added it will still receive those later notifications.
