Cleanup and optimize particles

Minor improvements while going through the particles sources:
- Reduce getShadowDatum() calls
- Remove unused m_lastLevel, reloadColor(), m_available
  m_velocityFromMovement, maximumAlive, m_pending, m_lastT,
  m_last_last_last_emitter, modelIndex
- Color4ub structs can be assigned directly
- Fix pri for shaders_ng files
- Other minor refactoring
