Another small patch for 53c - not as important, but has one neat little feature: you can now mark a node as a "walking" node. If a node is marked with this flag, the bot will walk to that node, instead of running to it. Really useful for dangerous ledges, or tight spots where you need to be sure the bot stays on the path. 64 is the "walking" node flag.
Crapshoot: I added the changes you requested too.
Cheers!
