Galleries should support three link types:

* Media File: [gallery link="file" ids="1,2,3"]
* None: [gallery link="none" ids="1,2,3"]

Although the third parameter currently works when false to indicate
no dependancies, it works by side-effect, the function signature uses
an empty array to indicate no dependancies.
