[RFE] Distinguish License Name and URL in XML Output

Currently the OWASP Dependency Check (v3.1.2) is outputting license information in the XML format as text inside a single `` element, with the name and the URL separated by a colon and a space `: `

For example:
```
The Apache Software License, Version 2.0: http://www.apache.org/licenses/LICENSE-2.0.txt
```

That is a combination of the license _name_ and the license _URL_. But when parsing the license, I would like to distinguish the license name and the license URL.

Request: please provide separate access to both data items.

Since backwards compatibility may be a requirement, I suggest to introduce new XML elements. Also, for forward compatibility purposes I suggest to let the structure support multiple alternative licenses.

Suggested new format:

```

The Apache Software License, Version 2.0: http://www.apache.org/licenses/LICENSE-2.0.txt

The Apache Software License, Version 2.0
http://www.apache.org/licenses/LICENSE-2.0.txt

```

Notice that the suggested syntax for `` is equivalent to what is used for ``.

Note: Later on, we could add things like `confidence` and `evidenceCollected`…
