[HOWTO] Show cpu cores in admin system tools

[qisback]

Cheers for making the patch.

I was considering doing a patch however I'm a great beleavier in "Give a man a fish and he will eat for a day; teach a man to fish and he will eat for a lifetime"

Meaning I tend to show the steps taken and then allow people to follow them rather than just produce a patch and have people ask why it doesn't work with there perticular version.

Although in future if it's the prefered way I'll create patches for any thing I do.
