Added sum reduction. NOTE: Scalar sum does not pass the automated test but vector sum does. I couldn't see anything wrong with the code itself and I strongly suspect that the failures are caused by loss of precision due to summing a huge amount of numbers of different magnitudes. However I'm not yet completely sure. Something like the Kahan summation algorithm might be useful if the errors are really caused by fp arithmetic.

The previous commit to ac_mkbuilddir.sh was not enough. Added a line that makes the script to stop if any of the commands fail to avoid cluttering the base astaroth directory. In my case the issue was permission denied when trying to create a project directory in /MYSCRATCH (system root directory) instead of MYSCRATCH (astaroth/MYSCRATCH)

ac_mkbuilddir.sh did not stop if the directory specified by the user did not exist. This lead to messing up the base astaroth directory with temporary cmake files. Added -p flag to mkdir to create parent directories if necessary to avoid this

Added declaration of constants for sink particle. Still in the process of understanding how values are passed, but I've realized how physical equations are defined in stencil_process.sps and in principle I can replicate that for sink particle(which will mostly be gravity).

Apparently my edit this time was unsuccessful, tons of error messeages showed up when I ran "make -j" command in working directory. However this commit is mainly for education purposes, it's so that Miikka (main) and others can see what I changed easily and can use as teaching reference.

Moved more stuff out of astaroth.h to astaroth_defines.h. I'm not particularly sure what's the best way to arrange the include files. These changes are just for readability so it's very safe to move things around though.

Added overloads for getting and setting various parameters. However, the compiler mangles the names which is not good for a cross-platform library so the functions are commented out for now. Sadly _Generic, which would solve everything, from C11 is not available in C++.
