Modify proc stats to show new memory use computation.

Switch the proc status UI's memory use bar to be based on the
new total memory use computation, instead of showing that weird
"time spent in memory states" thing.

Also now have it link to a detail page that shows details of time
spent in memory states and RAM used by various things.
