[Bug] Fortiguard: Category parsing does not handle "-"

[srilumpa]

Describe the bug
Categories such as "Web-based Applications" or "Web-based Email" are not properly pared and identified by the Fortiguard_URLCategory analyzer.

To Reproduce
Steps to reproduce the behavior:

1. execute ./urlcategory.py <<< '{"data":"http://trello.com","dataType":"url"}'

result is:

{
  "artifacts": [],
  "full": {
    "category": "Web"
  },
  "success": true,
  "summary": {
    "taxonomies": [
      {
        "predicate": "URLCat",
        "namespace": "Fortiguard",
        "value": "Web",
        "level": "info"
      }
    ]
  }
}

Expected behavior

The result should be:

{
  "artifacts": [],
  "full": {
    "category": "Web-based Applications"
  },
  "success": true,
  "summary": {
    "taxonomies": [
      {
        "predicate": "URLCat",
        "namespace": "Fortiguard",
        "value": "Web-based Applications",
        "level": "info"
      }
    ]
  }
}

Work environment

• Server OS: Debian stretch
• Cortex version: N/A
• Cortex Analyzer/Responder name: Fortiguard_URLCategory
• Cortex Analyzer/Responder version: 2.1

Possible solutions

• use regex [-\w\s]+ instead of [\w\s]+ to parse URL category from the API response
