Generate a simple table indicating software versions

During meeting on September 5, 2018, client requested to have a simple table of used software and versions in the output project.

The rationale being that this would be an easy way to tell what was used to generate the data, apart from walking through the packed CWL, reading the HTML methods document, or visiting the website to review the description

The request from the client was a simple two-column CSV file such as:

```
"Software","Version"
"FastQC","0.11.4"
"GATK","3.8"
...
```

I agree that having such information be easily discoverable is a good idea. I think this should be a part of reworking our reports documents.

One thing that's not clear to me - does this relate to #32 ?
