Quality of Life Improvements

Several updates to the gameplay and mechanics to improve playability and add some degree of challenge.

• Increased rover mass and lowered it's center of gravity to help prevent rollovers
• Swapped the rotating lights for blinking ones (still needs some tweaking)
• Removed the rover's amber light and replaced it with a more detailed power supply box and a cargo bed.
• Added 3 new goals in the form of CO2 Scrubbers on the front of each hab module
• Added pause (esc key), win and fail dialogues with options to continue, restart or quit (quit doesn't work on the web)
• Added a status UI with the status of each goal and the time remaining above it.
• Added a communication chart at the top left to visualize the control lag/delay.
