Added a differenciation between AssociationCollection#size and -length. Now AssociationCollection#size returns the size of the collection by executing a SELECT COUNT(*) query if the collection hasn't been loaded and calling collection.size if it has. If it's more likely than not that the collection does have a size larger than zero and you need to fetch that collection afterwards, it'll take one less SELECT query if you use length.

Removed authentication framework as xal made me realize that with noradios conditional filters, it was actually more code to use the framework than doing it by hand. Killing a darling! Props to noradio for the patch and xal for the nerve to stand up and question the captain before the plane crashed. Oh, and a pad on my own back for walking away from a couple of hours of work without getting pissy
