Improving on how it handles the lookup for an already added node:

  * Added labels
  * Added "prepare" type approach of query
  * Added some escaping

Also cleaned up the logging.

Apparently just doing the "prepare" with Neo4p doesn't seem to
do all the escaping, need to look into more.

Also tweaked the stylesheet a bit .

Still having some errors with the import since
the refactoring, but want to push out improvements before lunch.
