An anagram is defined as

1. the same letters
2. rearranged
3. to make a new word

The existing assertion only checked the presence of the expected word,
but did not explicitly exclude the existence of results that match the
input exactly.

- Especially in the earlier exercises, let's make it one less
  error that folks need to track down.

scrabble-score: replace illegal word

multibillionaire can't be played as a word in a real scrabble game.

Revert "Move example source into a conventional source root location."

This reverts commit c2657807be96bc6aecfc34781ca6963477b1fe29.

If we want to do this, we'll need to do it more systematically to
avoid breaking the build and confusing people who may be used to
finding the solution in a particular place.

- includes @Parameters attribute that allows you to define a template for names of tests, making the test output far easier to follow.

- makes it easier to work on a solution when you can one-step define the source root containing the example.
- one step toward making it easy to run unit tests against example solutions in CI.

- fixes exercism/x-api#59
