Show info about Scooby in the report

[banesullivan]

We should also add a header line to show info about the version of Scooby being used to make the report. Perhaps something light-hearted and simple like:

>>> scooby.investigate()

For the widest possible adaption I would opt to keep it very dry and simple. How about reporting scooby in the empty field below 'machine', right of 'RAM'? Or just in the section of numpy etc...

I think it makes the most sense to put it in the Python package section if not in a preamble. I just changed #15 to the following by putting Scooby's version in the report's internal dictionary of package versions (and since it's Python 3, the order is preserved so scooby would always appear first)
