make crawl sync bug fixes.
fix Puz crawl from dying out on host 9
because spider reply did not resuscitate waiting
tree for its ip.
fix mike's zola crawl with a repeat of 3 days
from not incmreneting the round because it had
maxrounds 0, which means to ignore... assume 0
means to ignore now. send out 0xc1 crawl info
requests to even dead hosts so we can at least use
their last known good info.
fix up round incrementing logic.
show if coll has urls ready to spider in html page
contains a hack fix to fix things at startup
but now it is commented out.
