Rollup commit for many collective refinements. See #54, mostly:

  • reference variable for DNSAdmin link URL
  • remove stale fields from listSubs() return
  • docucomments in getTypeList()
  • accept "description" as an alias for "desc" in allocateBlock(), to better match updateBlock()
  • refine selection of the IP to assign based on the VRF when called with a bare IP - mainly useful for RPC where the pool ID might be hard to come by
  • further refinements in keeping the VRF tagged on allocations more like the master_id; invariant once originally set rather than a freeform per-allocation field
  • refine RPC calls for DNS updates on successful allocation
  • add a hook/flag to allow assignment-by-update on pool IPs, mainly for RPC
  • refine RPC calls on allocation updates
  • make deleteBlock() smarter so that the caller can just pass the type in
  • refine returns from getBlockData() for various call points
  • tweak internal lookup chain retrieving rDNS info and reference pointers
  • add a sub to retrieve the rDNS zone ID (or IDs) that matches an allocation
