Updated rymdsond

Rymdsond WIP has been updated with following fixes:

• The transmitter is now guaranteed to spawn further away from the start location
• Slight optimisation to visibility updates when cams are on

I got great feedback from @krystman, @TobiasBieniek, and @NerdOfGamers on Twitter with things that they found that are needed to be fixed. Hopefully I'll have some time to fix some of them in upcoming weeks along with some UI improvements.
