Introduce the notion of a 'sample comment'.

- presence of the sample's reported.by file is now mandatory.
- when saving a sample, reporter name & URL are queried, to avoid operator forget about creating the reported.by file.
- when saving a sample, one can store a few-liner comment.
- when recalling a sample, the reporter name, URL and comment (if present) are printed.
- update the powerpc-e500v2-linux-gnuspe sample to include Nate's comment (from his original mail).
- update all samples that were missing the reported.by file.
