REWRITE: Introducing: More bits for Song Changed SC_* flags.

Added MusECore::SongChangedFlags_t (in new type_defs.h file). Declared as int64 type.
All Song Changed parameters, handlers, connections, calls, colateral operations etc. now use 
 this new SongChangedFlags_t. 
All the handlers are now ready for the code bodies to accept any extra flags, devs need not
 do anything more than define new SC_* flags and write support inside the handlers.
Please beware these possible extra flags when writing songChanged handlers and setting updateFlags.
