DoN's 3D-Pathfinding / Flying-AI system (with full source!)

@MatzeOGH - Nice! I do have a major update coming soon (with a big surprise feature!) but 4.11 is what I’ll be using for that too so feel free to port to 4.12 as you like.

@UCF - Thank you. For newer versions most issues are engine-level API changes/deprecation (unrelated to the plugin itself) so getting the plugin to work shouldn’t be a major issue. The real challenge will be making sure the all the usecases that your project needs are met in a reasonable manner by the system. Playing around with the sample project should give you an idea about its strengths and weaknesses…
