Title: Add enable support for build packs

I decided to go ahead and just expose an enabled and disabled flag rather than wait for the optional support.
To some degree it makes more sense to do -enabled or -disabled rather than -enabled or -enabled=false (disabled).

As part of this I also fixed the issue with position and made it a String flag.
