Message:

• 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)
