In fivestar_form $current_vote is referred as scalar and class

In fivestar_form() $current_vote is currently referred as scalar and class. For anonymous users it is '$current_vote = 0;', but for logged in users it is 'votingapi_get_vote(....)', which returns object. Later in the code $current_vote is used (once) as $current_vote->value.

I'll attach a patch that changes '$current_vote = 0;' to '$current_vote->value = 0;' - simple, almost cosmetic change.
