tweaks to display of number of cores in Resource tab

[Pavlos Kairis]

Not a bug but an enhancement ... I have 6 cores (AMD FX 6300) and the resource tab shows 4 cores as the first row and 2 cores in the second. It would look nicer to line them up as 3 on 1st row and 3 on 2nd row. Also, note the vertical spacing between cpu1 and cpu5; too tight.

Thanks.
