Add missing #include <stdbool.h>

[merkys]

GNU 14.2.0 CXX compiler on Debian unstable complains about missing #include <stdbool.h> in a bunch of *.h files, for example:

[ 27%] Building C object src/CMakeFiles/mychem-lib.dir/property.c.o
In file included from /home/andrius/src/mychem-code/src/property.c:30:

This PR makes mychem-code compile successfully for me.

Thanks for reporting the issue. Is it not sufficient to add the missing header only in the header files?

Good point, I have not tried that, I directly followed GCC advice. Will check.

You were right, it is enough to add the missing header to header files.

Updated the PR accordingly.

The file property.c still includes stdbool.h. Can you please remove it?
