Now diablo.h is treated in the same way as all other header files of
Source, as it only contains the declarations of global variables and
functions of diablo.cpp.
Besides consistency, this also enables mods to include diablo.h just
like any other header file without having to include every header file
(and without having to include C++ specific aspects of the now all.h).
While no storm functions are called from these source files
it is determined that they included storm in the original
source files as made visible by the inclusion of infinity
in the data segments of the respective source files.
