[PATCH] ui-snapshot: filter permitted snapshot requests

[john at keeping.me.uk (John Keeping)]

Currently the snapshots configuration option only filters which links
are displayed, not which snapshots may be generated and downloaded.
Apply the filter to requests as well to ensure that the system policy is
enforced.
