counter() complains about `amount`

[ivulfson]

    my $doc = Couchbase::Document->new('test');
    $CB->counter($doc, { initial => 1, amount => 1 });

You get this warning:

Unrecognized key 'amount' at ./t line 24.

but the increment actually works (i.e, value does get incremented).

[ivulfson]

As an extension of this bug, decr() is broken, since you can't specify amount=>-1.

The correct parameter is delta. Do the docs say amount? If so, I should fix one or the other. Not decided on which one makes more sense, though.

[mnunberg]

Oh, I see, the docs use amount.

[ivulfson]

Yep, that works. :)
