- New behaviour for gas grenades:

Gas grenades now don't cause direct damage on hit anymore. They will cause damage on start of turn or if you move inside a gas cloud. Of course gas mask still helps (except for creature gas and fire).
Every tile moved inside a gas cloud deals a percentage of the normal damage (default 10%). This is set in Item_Settings.ini (DAMAGE_HEALTH_MOVE_EXPLOSIVE_MODIFIER, DAMAGE_BREATH_MOVE_EXPLOSIVE_MODIFIER).
Tiles can now have multiple gas effects on them. Unfortunately this is not visualized (yet).
Smoke doesn't make a character immune to other gas types anymore.
The 25% chance of taking damage while moving through a gas cloud has been removed. Damage is now applied 100% of the time.

- New modifiers for explosive damage in Item_Settings.ini (DAMAGE_HEALTH_EXPLOSIVE_MODIFIER, DAMAGE_BREATH_EXPLOSIVE_MODIFIER). These could fully replace EXPLOSIVES_DAMAGE_MODIFIER in Ja2_Options.ini but I left that general modifier untouched for now.

- Some compiler warning fixes.
