v0.22.3: A trial by fire

Changed

• The Flamethrower is standard issue. Every account owns it from the first run. The starting kit works better with a close-range weapon in it: the flame is the answer when something slips under your guns, and the opening waves already fall inside its short reach.
• The Balloon Mines moved into the Arsenal. Same weapon, now a 300 flux purchase like the rest of the shop. If your runs were built around minefields, one run's harvest buys them back permanently.

If you had already bought the Flamethrower, you simply own it a little more officially now.
