Last major perlcritic session (w/o using Readonly)
Convert Readonly to greppable comments
Retracted use of Readonly module, now using commenting conventions (put CONSTANT or CONFIGURATION in comment on same line if known acceptable, safe, usage)
avoid global counter for naming improperly named pages
perlcritic cleanup (hopefully stepping on no toes)
fix regular expression constants to avoid peculiar confusions about the x modifier applied to character classes
