Deprecate exercises

[keiravillekode]

Three of our current exercises are marked as deprecated in problem-specifications, and they have replacements that are implemented.

We can mark the exercises as deprecated in config.json

accumulate -> list-ops
beer-song -> bottle-song
binary -> all-your-base
