hot new features straight from the feature-press

what's rolled off the feature production line this week? some extra hot new feature-code-game, that's what:

• new item, the oxygen mask. provides oxygen when worn.
• broke previous oxygen consumption system because it was happening client side for some reason fixed this, standing in air will now let you breath
• every american should have an oxygen generator in their basement. new tile feature, oxygen generator.
• ovens light up when you use them.
• can't walk through large objects like the reactor as if they weren't there anymore
• reworked a bunch of busy floating ui panels into one awkward side panel that's even more in the way and ugly to boot

all this and more, although the 'more' might be code reorganisations that only benefit me. ciao!
