Host code now compiled according to the C++11 standard. The device code has used C++11 for a while now and it's good to use a single standard consistently throughout the project. Old Intel compilers (~14.0) do not seem to support C++11 but the code should still compile since the flag is ignored in that case.

Because produces cryptical messages preventing compilation. The messages do not
tell anything about the problem and are also at odds with some gcc specific
pragma commands. If we can resolve these issues, we can turn it back.

Overhaul to the user-defined parameters done: All logical switches, parameters and vertex buffer handles are now defined in a single header file (the default location is acc/mhd_solver/stencil_defines.h). This header is used when preprocessing the DSL sources and is linked to the include/ directory when calling scripts/compile_acc.sh. astaroth.h is now used for configuring internal stuff only and should not be modified by users

Changed #if 0 to #if LFORCING instead to get the code to compile if forcing is used (even though autotesting does not support it yet). Also more autoformatting. Maybe I should disable it or then everyone should start using it to avoid cluttering commits with these superficial changes
