[GRASS-dev] adding spacetime datasets to element list

[Michael Barton]

To be consistent with other kinds of GRASS datasets, we should be able to list strds, stvds, etc from g.list. Because this will require some updating of other aspects of GRASS, as you note, it is good to start thinking of it now. Hopefully, you won't need to do this all since there are are others who are familiar with these modules once your format for the datasets is stable--and because you are doing all the work with the temporal modules.
