Upgrades to Document Library for 2.0
Document Library in Social Office 2.0 now natively supports having documents and folders on the root folder.
This upgrade will move all folders in the previous "Document Home" to the most root folder.
Note, it is now required if you are using FileSystemHook to have the "dl.hook.file.system.root.dir" property set to your file repository before upgrading.
Otherwise the upgrade will fail.
