en-US: craftError string changes

Craft, CraftWeapon etc etc. GeoscapeState::time30Minutes(),
- do NOT use 'STR_READY' to mean not ready.
Instead, set a Craft-class boolean var "stopWarning" to accomplish
not spamming the player with no-fuel and/or no-ammo messages.
- rewrite Craft & CraftWeapon rearm()
Production: rewrite fuel & ammo item-check for Crafts

DogfightState: bellcurve the stereo soundFX, center weighted.
ItemsArrivingState: check for fuel (not just ammo) to top up waiting Craft.
Craft: put in a bunch of consts for function parameters.
CraftInfoState: add + sign to show that Craft has stopWarning flag set.
- and so it will take longer than the time shown to refuel and/or rearm.
CraftsState: use "-" sign instead of "0" if Craft cannot use CraftWeapons
	or carry troops/tanks
InterceptState: format.
