CentOS -> Centos in pulledpork.conf about pulledpork HOT 3 CLOSED

I'll update the notes about the distro... essentially the options are 
Centos-4-4,
CentOS-4.6, Centos-5-4 and CentOS-5.0

These are what are included in the tarball, I don't see a way that makes sense 
to
handle programatically but will put some more thought into it.

Thanks. I didn't think about adjusting the code to handle this, just the 
comment line
listing the various precompiled systems.
