Basic Authentication in Cypher Session

Fixing issue #57

Fix for allowing basic auth parameters to be passed through to HTTParty the way it expects from Cypher Session.

There are other places where I feel this might be needed to be applied like cypher_transaction.rb and resource.rb. In short, wherever we have used HTTParty and we need basic auth to be allowed.

Having faced this issue, only in Cypher Session, I was able to test it effectively, but since I couldn't replicate the same issues with Cypher Transaction, I didn't touch that area.
