feature 2581: new design on albums list management.

icons removed, replaced by text links visible on :hover

better ergonomy for automatic order: the "save manual order" submit button
only appears when a change is detected in the album ordering. The "automatic
sort order" becomes a dedicated fieldset, hidden by default, displayed "on
user demand".

new virtual album form displayed only "on user demand"

cat_list, cat_move and permalinks are 3 tabs for the "Albums > Manage" link
in the menubar.

permalinks admin page slightly redesign: fieldsets instead of centered h3,
"on user demand" form to add/modify permalinks.
