level.labs() is live, new map

new level labs is done (it's kinda randomized, so expect it to feel different each run)
  (I know there are tons of bugs, but I figure we can find them together :)

foam gun now gets about 20% less ammo
new junk tech: "emergency broadcasting" - plays some fun sounds and gives you health

updated matter.js to a newer build matter-js 0.17.1 by @liabru
  (was matter-js 0.14.2 by @liabru 2018-06-11)
  matter.js patch notes suggest a possible 30% physics performance increase
  decomp.min.js was removed because I don't think it does anything anymore
    I did get one error message about it being missing, but there were other bugs too
