Rename ProcessList to ProcessTable throughout

Following up with some discusson from a few months back,
where it was proposed that ProcessTable is a better name.
This data structure is definitely not a list ... if it
was one-dimensional it'd be a set, but in practice it has
much more in common with a two-dimensional table.

The Process table is a familiar operating system concept
for many people too so it resonates a little in that way
as well.
