example is now actually a functional replacement for the 'exec/node list'
command (e.g. using 'jsexec nodelist') and a replacement for the hard-coded
Ctrl-U (who's online) handler. To install, run 'jsexec nodelist install'.
Supports modopts.ini [nodelist] settings (default to false):
- include_age
- include_gender
Other than the new age/gender options, *should* function identically to the
hard-coded nodelist() and whos_online() functions from getnode.cpp

global user object).
