Reformat "Critical" section to define "critical issues"
Reformat FAQ sections to follow a new format
Reformat FAQ sections so individual questions have links

All sections now follow a new format (below).
A "frequently asked question" may also include a possible
cause and a solution (if the two are not obvious from
the context):

all modules, and paginates all functions and classes onto
separate pages.
