- Moved place bonus hero before normal random hero and starting hero placement -> same behaviour as in OH3

- Moved placing campaign heroes before random object generation -> same behaviour as in OH3
- Refactored pickHero into pickNextHeroType (hero generation sequence) and pickUnusedHeroTypeRandomly
- Added a SIGSEV violation handler to vcmiserver executable for logging stacktrace (for convenience only)
- Fixed Fuzzy.cpp and VCAI.h compilation on Clang
- Added a handleException function in addition to our macros (no use of macros, enables debugging support, does not re-throw, catches ...-case too)
