[CentOS-docs] Edit permissions: quick cleanup of QaWiki/AutomatedTests

G'day

Wiki username: SteveBarnes

As per the guidelines on:

    http://wiki.centos.org/Contribute#head-42b3d8e26400a106851a61aebe5c2cca54dd79e5

I'd like to tidy up this page a bit:

    http://wiki.centos.org/QaWiki/AutomatedTests

I used it as the basis for developing my test scripts; the formatting for the code examples is a little wonky so I thought I'd tidy it up so others can read the snippets easier.

Cheers

Steve
