Deprecate deprecated exercises from problem specifications

[tomasnorre]

Resolves #813

I know the checkDeprecatedExercises isn't super nice, but it was the fastest way I knew to get inform about which exercises was deprecated.

I can look into the configlet repository, to see if I can incorporate the functionally there.

Output from script:

shell> php checkDeprecatedExercises.php
array(5) {
  [0]=>
  string(10) "accumulate"
  [1]=>
  string(9) "beer-song"
  [2]=>
  string(6) "binary"
  [3]=>
  string(15) "scale-generator"
  [4]=>
  string(7) "trinary"
}

There's nothing wrong with the checking file, I think. I only think about the location. Maybe put it into contribution/? Or actually make it executable (adding a #!/usr/bin/env php line to the front, setting +x file mode)?

Adding it to the PHP CodeSniffer exclusion list here should remove the strict types header requirement.

Looks good to me. Thanks for solving this problem!
