Changeset 8711 for code/branches/ai/src/orxonox/controllers/ArtificialController.cc

Message:

Bots are ready for rocket usage. (The hit rate for rockets is just about 60% though.). Note that this is just a proof of concept implementation. The next goal is a more generic implementation that adjusts the AI to any spaceship, not only the assff and similar ones.
