more SYSCF and related bits - cleanup and features

infrastructure for "system options" - things currently specified at build
 time that should be changeable at install time or run time but not really
 under user control
generalize contact info so it can be localized and it doesn't have to be
 an email address
move recently introduced WIZARDS into sysopt
drop bogus OPTIONS=wizards possibility
new function build_english_list() to comma-ize and add 'or' from a whitespace separated list: A.  A or B.  A, B, or C.
syscf file now handles: WIZARDS SUPPORT RECOVER
 SUPPORT specifies local support information
 RECOVER will eventually supply port-specific and/or localized info on how
  to run recover (or get it run for you).
Note: in sys/msdos I changed sys.o (generated from pcsys.c) to pcsys.o
Note: sys/msdos/Makefile.GCC has 2 rules for sys.o (now pcsys.o)
