Various improvements

- Only escape characters in "content" field, these can contain newlines.
- Trim newlines and tabs, etc from the title, id and author fields.
- Make decodefield, xmlencode functions easier to "chain" without allocatting
  new buffers.
- Move printutf8pad from util (only used by sfeed_plain) to sfeed_plain.
- Update README, still need to update the man-page and improve the documentation
  in general.
- Code cleanup.
