Changed generation of makefile dependencies:

Changed generation of makefile dependencies:
  * There are now two options, --create-dep and --create-full-dep. One
    will add system includes, the other not.
  * Both options require a file name. This is an incompatible change(!)
    but has the advantage that the user is in control of extension and
    path of the generated file.
  * Output will always include a phony target for the input files. This
    may not work with all make programs.
