"Date created" ambiguity

[jimsafley]

The use of "Date created" for a resource is ambiguous. For example, on the resource browse page, does the "Date created" column header signify when the Omeka resource was created or the resource's dcterms:created? The same goes for the "Date created" on the resource show page's sidebar.

It should probably be "Created" or "Item created" to distinguish from the dcterms:created property.
