lynx-dev [PATCH to dev18] Patch that allows to ignore document expiry dates

[Vlad Harchev]

 A tiny patch. I know it's cheating, but it could be useful for somebody with
 a slow connection. Feel free to change the name of the lynx.cfg option.

* Added new lynx.cfg setting named "documents_do_not_expire"  that, if set to
  TRUE, allows to avoid reloading documents that are expired or with 
  "Cache-Control: no-cache" set for them - VH
 
 Best regards,
  -Vlad
