replace validation with attemp to get outlinks - UNSTABLE
create function get_outlinks_and_populate() to replace validate_url_and_populate()
- validate_url_and_populate() is commented out where it has been replaced, just comment/uncomment to revert
add a call to setcache2(), like setcache one but shows index number of each url and reports inlinks as well
- outputfile is the same as setcache with a '+' appended
add output tracing for clean_links() when run on all urls after the root_set
