- refactoring of comments.php

- creation of function get_thumbnail_src used everywhere a thumbnail must be
  displayed

- creation of function parse_comment_content (used in comments.php and
  picture.php)

- concerning undefined index on arrays retrieved in database, instead of
  testing possibly unset values, use of @ operator (smarter...)

- add pre tag in default.css stylesheet for debugging purpose (need to have
  left aligned text)
