Tomes of X Spells and Spellbinder's Hat (and any other sources for such
bonuses from mods) will no longer provide spells that are banned on map.
Option is only active for random maps and for HotA h3m's. RoE-SoD .h3m's
work as before.
If needed, behavior can be changed in config
- Constructor of Identifier from integer is now explicit
- Lobby hero/town selection now uses Identifiers instead of int's
- Removed serialization workaround for hero portraits
- Added dummy objects for custom heroes portraits for ID resolver to use
- HeroInstance now stores portrait ID only in case of custom portrait
- Fixed loading of campaign heroes portraits on RoE maps
