Mehod -numberOfSectionsInTableView: is optional but not conditionally checked

Browse Source 
The documentation for `UITableViewDataSource` specifies that the default value is 1, and that its implementation is optional. However, ASTableView's forwarding doesn't account for the unimplemented case. The desired behavior is to return 1 in the case that the method is not implemented.
