[CentOS] Thank you: Wiki data for adding 3rd party repository, ProtectBase and Priorities

This is a public thank you, to whoever wrote the Wiki's for adding 3rd
party repositories, ProtectBase and Priorities. Clear, excellent, step
by step instructions. I did this late last night and I missed the thing
that Priorities is the recommended plugin, so I will change to that,
from ProtectBase.   :-)   Lanny
