* stripAnchorFromURL because stripURL because it now handles anchor and path suffix stripping
* and url tests were written to support this
* outputs status
* crawlStatus() function created (split out of docrawl())
* changed from using bool flags to linkType in single httpItem enum, tests updated to match this
