Make it possible to get ordered bind names

[exodist]

Makes it possible to know what column name is associated with every item in the @Bind array.

This is an ultra-quick way to achieve the goal. I would not be surprised if you had a better way to do it. But adding this functionality would solve my problem.

IF the new API of adding an arrayref at the end is too hacky, see https://github.com/exodist/DBIx-QuickORM/blob/master/lib/DBIx/QuickORM/SQLAbstract.pm

Could always add my ($stmt, $bind, $bind_names) = $sql->select2(...) without any need to add an arrayref at the end. Feel free to grab the implementations from the above link and just throw a 2 at the end of them if that idea is more palatable.
