Added stuff for the device layer for testing GPU-GPU MPI. This is a quick and dirty solution which is primarily meant for benchmarking/verification. Figuring out what the MPI interface should look like is more challenging and is not the priority right now

Various improvements to the MPI-GPU implementation, but linking MPI libraries with both the host C-project and the core library seems to be a major pain. Currently the communication is done via gpu->cpu->cpu->gpu.

Built-in parameters are now added during compilation instead of defining them in CUDA sources. IMPORTANT: DCONST macro should no longer be used when accessing built-in variables. Now all uniforms are consistently accessed with the handle only

New feature: ScalarArray. ScalarArrays are read-only 1D arrays containing max(mx, max(my, mz)) elements. ScalarArray is a new type of uniform and can be used for storing f.ex. forcing profiles. The DSL now also supports complex numbers and some basic arithmetic (exp, multiplication)

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.
