Add obj.save(override_file_path = None) function

[anatoliy-savchak]

Existing ToEE function 101662C0 signed int __cdecl PartyCreationPcSaveAndDestroy(ObjHndl handle) destroys the object.

Potential uses:

• Prepare PC programmatically;
• Export PC to other module;
• Prepare PC programmatically for higher level when module requires it;
• Save manually leveled up PC for further uses;

I tried this out. The game saves a character file, but having the file around causes a crash when you go to create a new game. So it requires work on the loading end to be viable.
