Allow for users in groups to bulk upload if the media is allowed in group

Problem/Motivation

I have media group types that group users can create, but only associate with said group bundles. They can't add these media item bundles outside of the group. I'm adding a gid query param to a button, then running a check when the user hits the form against the loaded group to see if the name of the group is contained in the media type. If it is, it shows up on the bulk form.
