Bug Fix: exp:eehive_flickr:favorites not working

Issue was first raised on StackExchange:

http://expressionengine.stackexchange.com/questions/2041/issues-with-ee-flickr-for-expressionengine-and-favorited-photos/2082#2082

Turns out that the call to phpFlickr::favorites_getPublicList() had the wrong number of parameters, and that offset was always resulting in no photos returned.

Happy Holidays!
