WIP - airstrike command

- Type `/strike [gps=x,y,surface] to send a large cloud of poison into the enemy
- Searches a chest near spawn for poison capsules. Current cost for command is 100 capsules but could be balanced.
- Needs market items adding for technology research, bought with coins.
- Variables strikeCount and strikeRadius start low. As the market upgrades are made (start at 5k each?) the size of teh strike and amount of capsules increases.
- Should be balanced to allow use from mid-game onwards. Don't allow early game use as manual throwing is fine for early outposts. This should be to speed up the boring end-game clearing of worms.
