Diagnostic System Activity page looks bad in opera

[chris2]

In opera, the system activity text is centered rather than left aligned.  Firefox doesn't have this behavior.  There is a

<center>tag around the table that contains the text that causes this.

I fixed it by adding some css to the pre tag in the javascript on line 73 of diag_system_activity.php that fixes the alignment:  </center>

Looks like all of the pages that use that same style (pfTop, pfInfo, etc) also suffer from the same issue. Should be an easy fix if that bit of css does the trick
