Introduce Row and Table classes for screens beyond top-processes

This commit refactors the Process and ProcessList structures such
they each have a new parent - Row and Table, respectively.  These
new classes handle screen updates relating to anything that could
be represented in tabular format, e.g. cgroups, filesystems, etc,
without us having to reimplement the display logic repeatedly for
each new entity.
