Updated run script to distinquish between applications and libraries

Necessary to improve the install reliability of software and
associated libraries (extensions). There is now a split between core
installation of applications and associated libraries. This is a loose
split since everything in the *Install* category is mostly
applications but also contains related setup while the *Libraries*
category requires a machine reboot so the fully configured environment
is loaded to ensure all libraries install properly.

The specifics of these changes will be handled in the corresponding
macOS Configuration project.
