Restrict Options Count to Match Maximum Number of Choices

It doesn't make sense to me that when the number of choices is restricted the ranking options still has options equivalent to the full list.

If you agree, it's a simple fix. Change line 86 of ranking module to:

    $num_choices = ($node->maxchoices) ? $node->maxchoices : count($node->choice) - 1;

If you want I can roll a patch.
