fix typo in method name "DeleteAll" should be "deleteAll"
change generated "deleteAll" SQL for mysql and postgres, dropping the " WHERE 1" because the underlying drivers do not except that as valid syntax (even though I am *pretty* sure it acceptable SQL)
update tests to reflect the changes in the generated "deleteAll" SQL statements
fix "deleteAll" update query (used when "paranoid" setting is active) so that valid "values" and "options" arguments are passed to the QueryInterface instance
implement more tests for "deleteAll" (test that it respects a models "paranoid" setting)
