Delegate comparison not correct

[pcolton]

Pixate Freestyle uses an NSProxy for the delegate, which causes ADLivelyTableView to go into a recursive infinite loop. The cause is that the check in the setDelegate method is using == vs isEqual. It should look like this:

- (void)setDelegate:(id<UITableViewDelegate>)delegate {
    // The order here is important, as there seem to be some observing done on setDelegate:
    if ([delegate isEqual:self]) {
        _preLivelyDelegate = nil;
    } else {
        _preLivelyDelegate = delegate;
    }
    [super setDelegate:self];
}
