Sulfur: Explosive, Geyser boost and Meteor Defense

[UberFubarius]

An idea for new tool and building based on sulfur. 

Explosive: a new material produced in a refinement building (molecular forge?). Takes sulfur, refined coal, and lime. 

Fracture Geyser: requires delivery of explosive to geyser. When applied, will give geyser "Fracked" status for a few cycles, which gives geyser an X% increase in production while active, or X% of its normal production while dormant. This gives late game base a way to boost geyser production of the stuff they want. 

Meteor Defense Cannon : a building with similar range as space scanner. Requires delivery of Dynamite and small amount of refined metal to charge up the Meteor Defense Cannon with X shots. Whenever a meteor enters the range of the Meteor Defense Cannon, it will fire one shot to explode it (meteor behaves as if it hit a block when hit). This give late game player a way to keep space open (for better solar, gas grass, and simpler rocketry) during meteor shower. 

Firework Stand: recreational building, consumes explosive on use. Dupe set off small firework in the area during downtime and give nearby dupe morale bonus.
