durk ce084ab1c5 Two minor (codewise) fixes to ensure everything works as advertised:
- Make sure to initialize the groundnetwork after succesful loading.
 - Ensure that the AI groundnetwork code proximity detection code used the
   correct values for bearing. (Note that detecting the proximity of the
   user aircraft appears still to be broken. I'll look into that later).
