Changeset 172 for trunk/gui/scripts/moleculeViewer.tcl

Message:

Fixed the download button so that it doesn't force the
analyzer screen to be too big, and so that it disappears
gracefully when squeezed out.

Fixed the molecule viewer so that it handles the case
where one molecule is empty and another is not, and
they're being compared with the comparison dial. Was
chocking on the empty molecule with no xmin/xmax set.
