Description of problem:

Current CMS 6 does not display sort items in any intuitive manner.

Following modifications allow to :
1.
display items within a folder in an alphabetical order, sorted by
name, case insensitive.
(admin ui : content section page, 'browse' tab : right part :
paginated display)

2. 
display folder tree in an alphabetical order, sorted by label, case
insensitive.
(admin ui : content section page, 'browse' tab : left part)



Code modifications for point 1 (in CMS) :
in com.arsdigita.cms.ui.folder.FolderBrowser.getTotalSize(Paginator,
PageState) :
replace line :
itemColl.addOrder("item.name");
by line :
itemColl.setOrder("lower(item.name)");

Note : original line resulted in a query that sorts the following way
: order by st_.is_folder desc, st_.item_id desc, st_.name


Code modifications for point 2 (CMS) :
in pdl/com/arsdigita/content-section/Folder-queries.ora.pdl :
in query getSubFolders, 
after line :
     group by f.label, f.folder_id
add :
     order by lower(f.label)

in query getSubFoldersWithPermissions,
after line :
      group by f.label, f.folder_id
add :
     order by lower(f.label)

Do the same also for postgre.
