Feature: Remember process/window list sort preference

Persist the sort column and direction chosen via the list header so the
next time the process or window management dialog opens it defaults to
the same sort. Process and window lists are remembered separately
(list\ProcessListSort and list\WindowListSort registry keys) since their
columns have different meanings.
