Separate Permissions for Create/Delete Files & Directories

[K-J-VV]

Currently, permissions for files and directories are linked together. It would be nice to separate these so that only select users/administrators have full control of the repository's hierarchy/structure.

i.e., admins are able to create folders/directors, standard users are only able to upload files within already existing folders.

Reason: To prevent user's from creating a chaotic mess of unorganized sub-folders
