Conformity with the XHTML 1.0 transitional standard

Creation of the following files :
- template/default/header.php and template/default/footer.php to ensure a common standard
- default.css to be CSS valid
Obsolescence of the following files :
- template/default/theme/conf.php
- template/default/style.inc.php

Custom galleries should reflect those changes.
