Significant changes in project files:

* added configuration for x64 builds
* lib/ERMScriptModule.cpp

More jugglery with callbacks. Moving stuff from CGameState to CGameInfoCallback. Work on unified game events interface for player (AI or GUI) and script module. Directing events to ERM interpretetr, first attempts of calling some triggers. Crashy, if there any scripts.
Some other changes, including fighting amount of includes in includes and tracking of hero visits (need further work).
