Fixes following issues: #625 , #1067 , #1212 , #1472 , #2072 , #2235, #2964
- Trails in `renderableTrailTrajectory` now goes through the spacecraft when using `AccurateTrailPositions`.
- Trail fading controls have been improved for classes using the `renderableTrail` class.
- `renderableOrbitalKepler` (asteroids/satellites) can now be rendered as both trails and points (or both at once). Solution implements similar functionality/controls as `renderablePointCloud`.
- Default setting for SweepChunking has been changed from `true` to `false` (iterative calculations of `renderableTrailTrajectory`).
- Some fixes related to missing points or off-by-one errors related to trail rendering
