Fixed Firestorm health.
- Fixed medikits having wrong TUs.
- Fixed starting funding calculation.
SO MANY BASE DEFENSE BUGS:
- UFO wasn't removed after base defense
- Base stays "inBattlescape" if base defenses succeed
- UFO would still trigger base defense even if it missed the base
- Crash if UFO was destroyed in base defense while being chased by craft
- UFO still wasn't removed if game was saved during base defense
fix game over state palettes
correct behaviour for explosive radii

a lot of explosive radii were actually HARD CODED into the original,
all grenade type explosions for example were limited to a radius of 5,
CyberDisc explosions were set to 6
all "waypoint" weapons were hardcoded as 10
tile explosions were at power / 10
HE/stun were at power / 20
incendiary explosions were at power / 30 (40 for ai/reaction shots)
fixes for "select next player" behaviour

we should have two flags here, one to SET reselect and one to CHECK reselect
because we don't always want to do both.
whoops

forgot some arguments.
fix for unresearched items in base defense
a few more fixes

correct faction calculations at turn's end to account for mind control.

use the correct check for the "researched" flag when excluding items from
base defenses

count UNresearched items as artifacts, not researched ones, and count
corpses regardless
