Allow Primary User of Headless Version to Add Local Media

[jaruba]

I'm still uncertain if this feature should be added or not, letting only the master account add local media is obviously better for security, but then it's not possible to add local media at all in the headless version.

Maybe this feature should be rethought for the headless version, and any user (or just the primary user) could be allowed to upload local files to the server to make them available for streaming? (but this would allow only user side local media to be added to the server, instead of server side local media..)

Maybe a better way to do this is to add a command line argument that would add local media on the server side, this way only the admin of the server can add local media.
