2.0.0

There are now just 5 kinds of formulas:

• salt({{x}}): query without FROM, with check of the result.
• salt(sum(hash) OVER ()): basic query, without aggregation in the first SELECT.
• salt({{x}} + sum(hash) OVER ()): idem, with check of the result.
• salt(sum(bit_xor(hash)) OVER ()): query with an aggregation in the first SELECT and/or a GROUP BY clause.
• salt({{x}} + sum(bit_xor(hash)) OVER ()): idem, with check of the result.

Here, {{x}} denotes a value entered manually by the user to check the result. hash is a shortcut for an addition of coerced hashes, i.e., nn(A.hash) + nn(B.hash) + nn(C.hash).

Some tokens have changed, but the queries should be unchanged.
