Per-process CPU history now also graphed when viewing Active Processes

I just completed the little bit of code to allow the per-process CPU history (white line) to be drawn whether you are in the All Processes or Active Processes tab. For those unfamiliar with this feature, when one or more processes are selected in the list, the cumulative CPU history is drawn on the graph as a white line.

In compliment to it, I also enabled the CTRL-A accelerator for this tab. Yes, these are little things that I should have done in the first place, but they are done now.

On to more important items, and I really must quit posting such trivial improvements here, lol ;). If I keep writing a page on every change, this is going to be a long blog. It won't slow me down though, I type much faster than I think ;p.

(changes to be in v3.99.9)
