not every neighbors are listed

Sorry, i'm too lazy to check which are bugged because i've made my own optimized modification of your code. If you want to look at it - https://github.com/shdpl/AS3-AStar .

It's ugly as hell because it has to be fast. That's all. I optimized only query's currently.

It's not marked as fork, because i've been experimenting with my custom quad-tree based thing, but it moved too slow.

Thanks for your code.
