Handling some issues in enrichment data generation (closes #76)

Before this change, it was outputting data in the tiq-test csv as below, because the tuples were one inside the other:
`````
"128.130.34.185","IPv4","outbound","http://www.nothink.org/blacklist/blacklist_malware_http.txt","","2014-09-15","[u'679',u'Vienna University of Technology',u'AT',u'',u'msus.tuwien.ac.at']"
``````
Now, it is rendering correctly as:
`````
"128.130.34.185","IPv4","outbound","http://www.nothink.org/blacklist/blacklist_malware_http.txt","","2014-09-15","679","Vienna University of Technology","AT","","msus.tuwien.ac.at"
`````
