Settings entries cannot smuggle auto-mode region markers

Settings entries containing auto-mode region markers are refused so they can't pose as classifier structure.

What

Settings entries containing <cc_automode or </cc_automode are now refused. Those tags mark off sections of the text auto mode's classifier reads, so an entry containing one could have posed as classifier structure. This joins the existing refusal of invisible and bidirectional characters and of literal <settings_ tokens.

Evidence

region tag; entries must not contain classifier region markers.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
