Rewrite build script for MPCDF systems
Description
The new script detects if modules are already loaded and loads them only if necessary. Thus it also works with sets of user-defined modules. There is a separate script for loading the modules that can be used also for different toolchains (e.g. intel) and pfft-based builds.
The scripts have a few command line options that can be displayed with the -h
option.
Also, the presets are removed.
