user wants to see testing procedures, guidance, and PCIv3 on proofs#edit and proofs#new

This commit contains a prototype of what I’m looking for from a seed
file. This csv needs to be populated with testing_procedure, guidance,
and description. The PCI Requirements can be found here: https://www.pcisecuritystandards.org/documents/PCI_DSS_v3.pdf

* The current seed file is based on PCI v2.0 and so we also need to
upgrade the descriptions to v3.0.
* `\n\n` and `\n\n-   Is kept`  is markdown syntax for new lines and
bullet list
* I broke how new lines work when I removed this method `.gsub(/\\n/,
“\n”)`. I know its important but when it was in, I couldn’t get it to
work.
