Hi,

This is a first attempt at a patch to read positions from DOT files. It
seems to import my dot files with positions just fine. It should work
for 3D as well as 2D- but I have only tested 2D. I don't know how to
handle the error messages- from looking at the rest of the code I added
a new one "importerDOT_error_posunreachable".

The position tag for the nodes should be of the form:

  pos="x, y"

It would be nice to be able to specify the size of the nodes too- I'll
look into that soon.
