Changes

Feature #10542

In Kmelia, removing a folder relocates it now, with all of its
subfolders and publications,  into the bin like the publications.
A folder is then definitively deleted when the bin is purged.

Feature #10542

When a folder and its content (both subfolders and publications) are put
into the bin, the actual operation operated by the KmeliaService is now
a move instead of a simple node detail update.
Rename the confirmation text when emptying the trash can.
When the trash can is emptied, the folders deletion is now taken into
account by the treeview.
Fix a bug with the number of publications displayed with the folder name
computed when a folder is deleted with its whole content.

Feature #10542

Add support of the feature in Kmelia with non-treeview
tree-structured documentation.

Ensure the feature works also for Toolbox.

Bug #14391

In Kmelia: when updating a folder within which the local rights are
enabled, the admin specific rights of the folder are then initialized
with the admin rights inherited from the parent folder. This behavior is
then coherent with the creation of a new folder with specific rights.
