Create a strategy for hosting old removed layers for archival links

[rhodges]

Options:

• Leave layer unchanged?
• Assign redirection of layer ids
• Alert users to removal of requested layer

[rhodges]

IDEA: Create special Theme called 'Archive'.

Like 'Companion', this would not appear in the catalog or the layer picker, but if activated via URL-supplied ID, it could still be called upon.
Additional feature might be to pop up an alert when users are seeing 'archived' layers, letting them know that 1 or more layers are no longer publicly available for browsing.
This could be expanded to A: Say which layers, and maybe even B: supply a new layer they may wish to use/view instead.
