Prevent f_package_add() from re-performing f_package_detect_installed()
even though f_package_config() may have already detected the installed
packages.
Add minor debugging.
Add the necessary code to uninstall packages (re-install still pending).
Both scripted access (packageDelete) and UI access have been tested
successfully with a variation of different situations including:
+ Uninstall a package which no other installed package depends
+ Uninstall multiple packages which no other installed packages depend
+ Uninstall multiple packages which depend on each other
+ Similar to above but when ordered removal requires tracing dependencies
+ Purposefully do things like uninstall a package that is not installed
+ Try to uninstall a package which other installed packages still depend
+ Try to uninstall multiple packages which other installed packages depend
+ And many more.
