v0.0.0.82 - Solar storm event

Have added a solar storm event. Make sure you have batteries/fuel cell on standby, as solar panel output drops by half when these occur!

Note I didn't release a devlog with last weeks v0.0.0.81 release, as it was mainly behind the scene stuff.  Lot's of improvements with graphics, that weren't a big deal but worth  doing. Also noticed the lighting library i was using was causing slow down issues. Only spotted this when i got round to testing on a different (faster!) machine. Which was pretty weird, so I've currently disabled that, as it may be slowing down the game for other people.
