Updated ACTIVEPATHSEARCH

- Changed "ACTIVEPATHSEARCH" to only work with real walls and not walls you can shoot through
* Seems the position lag for which I have implemented this no longer occurs on my client (was something changed?)
* Previous implementation prevented monsters from attacking you through shootable walls
* Special thanks to Michi for notifying me about this issue
