2 problems I've met

[Al538]

1. Sometimes it is not enogh 45 chars for name, so I had to increase it in schema.sql.
2. I've got exception
   File "/opt/nessus-database-export/export.py", line 181, in insert_host
   sev_count[vuln['severity']] += vuln['count']
   TypeError: list indices must be integers or slices, not NoneType

I think it happen when you have compliance scans.
Changes:
177-178, 208-209

for vuln in scan_run['vulnerabilities']:
    if vuln['severity'] != None:
        sev_count[vuln['severity']] += vuln['count']
