&overseer keeps history for individual processes.

Haven't shared in a bit since I've been doing a lot of background work that isn't visual, but I'm finally getting my UI all put together. &overseer finally has a functioning process list.

I'm off to a bit of a slow start with &overseer but I got a few simple charts and a good amount of other data collected that's not displayed, including CPU data for individual cores. We'll see how far I can get with process lists and metrics tomorrow.
