Bot's lights ow turn off when they are turned off.

Removed a shed-load of lights. Mainly ones right next to eachother and a whole bunch from the mining asteroid (it's a mining site not a god damn stadium!) Number of light_sources at round start has nearly halved.

Fixed the title-screen again because apparently it didn't commit last time.
Fixed some more broken icon_states
