[config.py] check if there are packages with inconsistent dependencies

[gaya-]

Use the functionality from asdf_check.py to print to the user every time when calling config.py which packages have inconsistent dependencies. For example, when typing $ python config.py cram_pr2_projection_sandbox the script should say, "warning: these CRAM packages have inconsistent dependnecies, use asdf_check.py for more details: cram_language ...".
