Provide details on folders

[Facyla]

Key informations that are very useful for users when browsing folders that have a lot of content:

• number of contained files and folders (at next hierarchy level only)
• overview of full number of contained files and folders (all levels)
• full folder size (all levels)
• max number of sublevels
