Major improvement: uniforms can now be set to default values. The syntax is the same as for setting any other values, f.ex. 'uniform Scalar a = 1; uniform Scalar b = 0.5 * a;'. Undefined uniforms are still allowed, but in this case the user should load a proper value into it during runtime. Default uniform values can be overwritten by calling any of the uniform loader funcions (like acDeviceLoadScalarUniform). Improved also error checking. Now there are explicit warnings if the user tries to load an invalid value into a device constant.

Added out-of-the-box support for MPI (though not enabled by default). Previously the user had to pass mpicxx explicitly as the cmake compiler in order to compile MPI code, but this was bad practice and it's better to let cmake handle the include and compilation flags.

Now CMake and compilation flags are functionally equivalent with the current master branch, not taking into account the deprecated flags. Also various small improvements to building.
...
Deprecated flags:
* BUILD_DEBUG. This was redundant since CMake also has such flag. The build type can now be switched by passing -DCMAKE_BUILD_TYPE=<Release|Debug|RelWithDebugInfo|...> to cmake. See CMake documentation on CMAKE_BUILD_TYPE on all av
* BUILD_UTILS. The utility library is now always built along the core library. We can reintroduce this flag if needed when the library grows larger. Currently MPI functions depend on Utils and without the flag we don't have to worr
* BUILD_RT_VISUALIZATION. RT visualization has been dormant for a while and I'm not even sure if it works any more. Eventually the RT library should be generalized and moved to Utils at some point. Disabled the build flag for the t

Reordered src/core to have better division to host and device code (this is more likely to work when compiling with mpicxx). Disabled separate compilation of CUDA kernels as this complicates compilation and is a source of many cmake/cuda bugs. As a downside, GPU code takes longer to compile.

src/utils is now a real library. Includable with the astaroth_utils.h header and linkable with libastaroth_utils.a. The purpose of Astaroth Utils is to function as a generic utility library in contrast to Astaroth Standalone which is essentially hardcoded only for MHD.
