Bonus * -> std::shared_ptr<Bonus>
This cures the following problems:
1) Memory corruption at exit. Some Bonus-es were deleted twice (mods?).
2) Memory leaks. Some Bonuses were not deleted.
3) Reduce the number of "Orphaned child" messages.
Valgrind reports 0 leaked memory now and no invalid reads/writes.
1) spell handler refactored to support modding in general way
2) imunnity icons moved to WoG as they depends on wog`s graphics
3) introduced new class template for handlers (todo: use this in other handlers)
4) save format changed
5) introduced "absolute immunity" - unaffected by "the Orb" etc. (todo: use it in config)
6) new format documented on wiki, added json schema.
* more split of registertypes - fixes 32 mingw build
- loading of all objects (including H3 objects) will be directed by mod handlers
- common base for all handlers accessible from mod system (IHanderBase)
- json format changes: use struct with string ID's instead of vector
- fixed some gcc/clang errors and warnings
- fixed several cases of memory leaks and invalid memory access (mostly related to usage of bonus system and/or identifiers resolution)
Note that right now loading is much slower than before due to excessive json validation (or not fast enough validator)
* introduced new handler BonusTypeHandler
* config\bonusnames.json converted to common format and splitted info main and localizable parts
* hanlders initialization refactored
