Subject: Enable/disable generating graphs depending on the target type

In CMakeGraphVizOptions.cmake you can now set GRAPHVIZ_EXECUTABLES,
GRAPHVIZ_STATIC_LIBS, GRAPHVIZ_SHARED_LIBS and GRAPHVIZ_MODULE_LIBS
to TRUE or FALSE depending on whether you want graphs for the
targets of the respective types.
