- admin/cat_options page added : manage options for the whole categories

tree (uploadable, commentable). status and visible will be soon added

- admin.php : $conf_link var to avoid lines longer than 79 characters

- config.upload_available configuration parameter disappear : it's simpler
  to manage with cat_options

- config.show_comments idem : new column categories.commentable, each
  categories can be commentable or not

- categories.site_id becomes a nullable column : a virtual category does
  belong to no site

- function display_select_categories has a new argument : $CSS_classes array
  to optionnaly assign a CSS class to each category in the select field

- added informations in include/config.inc.php for setting default value of :

  - categories.visible
  - categories.status
  - categories.uploadable
  - categories.commentable

- 2 new indexes images_i3(average_rate) and images_i4(hit) : optimizes best
  rated and most visited categories
