Added the 'Sato Gate' as a final dash gate for now. Added some more onto the end of the Test Tube, but still not sure if I'm going to keep this. (Let me know in the comments what you think).

- Made a few cosmetic changes
- Added a beacon to the Test Tube (The angle of entry works well to slow peeps down, which is needed to navigate it atm).
- Resynced wormhole gates as these seemed to fall out of sync and become a bit daft to get through.

Added a test gate. Not sure if I'm going to keep this or not, pending feedback.
