Highlights:

* BUG: Fix for a regex performance bug in http_servers when matching
  IPs. This was brought to our attention by @hudclark (#353)
* BUG: Fix for a CPE generation bug in which we were using deprecated
  CPEs. This was brought to our attention by @p0lr (#361)

  type (a,h,o) which provides much greater flexibility. (#361)

  (#341, #344, #345, #351, #354, #355)

  html_title, etc) fingerprints (#352, #357, #358, #359)
* Tooling: Adding field names (os.vendor, service.product, etc) to our
  standard identifier checks (#350)
