Include CRAN error/warning/note where relevant

[hturner]

For cases that produce an error/warning/note, such as Formatting Software Names, it would be good if we could include the message produced so that the cookbook may be discovered if people do a web search based on the message.

This does introduce a bit of a maintenance issue, as the message may change over time, but I think it will increase the usefulness of the cookbook.

I started adding the standard response from CRAN team members for the last recipes (e.g.: the .GlobalEnv issue). When we are done with (most) recipes, I will go through and add them for the earlier recipes as well.

Errors/warnings/notes from the automated checks are not implemented yet. The problem there is that I don't really see them when doing CRAN work as the packages are rejected before they reach me. I suppose those issues are more likely detected by package authors of the community. @jasdumas and I are discussing good ways, how they can contribute. We will also talk a bit about this in our time meeting next week.
