2.x vs 3.x

@Gleeok
sprite_list::swap isn't broken, It just isn't implemented. :p
Not going to bother commiting this @Saffith since it's most likely wrong. But I tried to fix it.

bool sprite_list::swap(int a,int b)
{
    // Re-added for now, but stil unimplemented.
    return false;
	
    sprite *c = sprites[a];
    sprites[a] = sprites[b];
    sprites[b] = c;
    uids[a] = sprites[a]->getUID();
    uids[b] = sprites[b]->getUID();
// checkConsistency();
    return true;
}
