First changes towards a special "isolated" edition

* Removed binary features
  - Removed companion
  - Removed orbital planes
  - Removed pulsar mass
  - Removed semi major axis
* Using triangle fans and rims to contruct complex beam cones (instead of simple quadric)
* Using wireframe model instead of textures (better cone feature visualisation)
* Using lighting only for spherical pulsar shape (doesn't yet work for cones)
* Adjusted pulsar rotation axis to line up with wireframe poles
* Adjusted initial view to be in line with rotation axis (as requested by Ben)
