Update turbolist3r.py

Edited analysis section to be more resilient against errors. Found subdomain candidates that began with a dot (ex .domain.com) caused the DNS query to choke. Modified exception catch block to catch unknown errors and continue around to try the next subdomain candidate.

+# Major changes to Turbolist3r from Sublist3r:
 # - check subdomain for text "From http://PTRarchive.com: " and remove it (otherwise it ends up in the output and can impede automated analysis with other tools)
 # - added functionality to query found subdomains, record answer, and catagorize as A or CNAME record. Speeds up subdomain takeover analysis as CNAME records and the services they point to are collected and displayed
