Replace ghemical in Debian Edu? (Was: Bug#826069: libghemical5v5: breaks color rendering and atom generation in ghemical)

[Petter Reinholdtsen <pere@hungry.com>]

Some background: The ghemical tool in Debian have a RC bug and might be
missing in Stretch (See bug #826069).  It is listed in a Debian Edu
metapackage (education-chemistry).  Michael wonder if perhaps we should
use a replacement:

Anyone know?  I do not know the tool myself, so I do not know if we
really want it included or can use a replacement. :)
