Automatically formatted all files via VS. This generally corrects indentation, removes trailing whitespace and corrects misplaced tabs or spaces. Manually tweaked a few files where required.
Changes included:
Warhead code split out of weapon code and refactored.
Warhead functionality now split into several classes, each handling one effect/impact.
Additional custom warheads can now be defined and called via yaml.
Custom warheads inherit the abstract class Warhead,
which provides target check functions.
Custom warheads have to define their own impact functions,
and can also define their own replacement for check
functions.
