Add "deep every" modifier

[pokey]

Would include all nested scopes, unlike default "every", which excludes them. So you'd say eg "quad wrap deep every key". Note that you wouldn't use this action with "take", as I don't think VSCode selections can be nested.

This should be trivial once we have #1523 as that adds a boolean to the scope handler that enables this behaviour

• Could add "<number_small> deep every" to limit depth. Might be extra credit tho
