made &spiderRoundStart=1 (or 0) force the next
spider round to begin.
also added pageUrl to XmlDoc::getContentHashJSON32()
so it's not included in the hash to fix some spider-time
deduping issues.
handle boolean query overflow errors better.
raise MAX_EXPRESSIONS
now use &roundStart=0 to trigger the next crawl round.
now assume all crawl jobs are "repeat", but those that
have repeat of "0" just assume 10 year frequency, 3652.5 days.
that way the &roundStart=0 will do another round of crawling
for them as well.
fix roundstart bug
fix &roundStart=1 again to force a spider round
for non-repeat collections.
