- Replace SMP real CPU group enable with individual real CPU enables.
I've had requests for this feature from people with 24 - 32 cpu machines
where there is insufficient vertical space for all cpu charts and they
want to split the CPU charts into multiple gkrellm stacks with --config.
- Add option to show/hide CPU panel labels so only a krell can be in the
panels. Not showing CPU panel labels saves vertical space - for systems
with medium to large numbers of CPUs. I find it useful with 4+ CPUs.
To make up for no panel label, added new chart label format string options
that draw the CPU label on the chart.
Temp and fan sensors cannot be relocated to CPU panels if labels not shown.
