vcmi/lib/CGameInfoCallback.h
Ivan Savenko 8353bca34f Small refactoring of adventure map spell casting: 
- Removed duplicated checks for DD possibility
- Moved most of spell-specific code from AdventureMapInterface to library
code
- AdventureSpellMechanics class now provides methods to check whether
spellcast is possible, similarly to battle spells
- If it is not possible to cast adventure map spell (e.g. no mana or no
move points) game will show infowindow immediately on clicking spellbook
instead of on cast attempt
- If hero does not have movement points for a DD, game will show correct
error message
- Added game settings 'dimensionDoorFailureSpendsPoints' due to
discovered H3 logic
