Function signature for function nodequeue_load_queues is misleading

Looking at function nodequeue_load_queues, the signature is nodequeue_load_queues($qids = array(), $bypass_cache = FALSE).

The $qids = array() suggests that calling nodequeue_load_queueswith no arguments is fine, and I'd expect to get all queues back in case i did not specify any qids to filter by. However, upon inspection of the code it turns out that calling nodequeue_load_queues with no arguments will return no queues.

I'd suggest changing the function signature to nodequeue_load_queues($qids, $bypass_cache = FALSE)
