Linked the defines used by the DSL and astaroth.h. Now f.ex. LENTROPY has to be set only once in acc/mhd_solver/stencil_defines.h and it is propagated throughout the whole project. The name for stencil_defines.h is not final and may change if I come up with a better name. In any case, there is now a standard header associated with each DSL solver where the user can set defines, and declare arrays (VTXBUF_LNRHO) and device constants (uniforms).
