update LAMMPS molfile plugin for VMD with element field support

hi all,

this is just a quick note that i finally got around to test
the support for the element field in the lammps plugin
for VMD. the changes have been committed to the VMD
cvs archive and thus will be present in upcoming releases
or alpha test versions. for people that don't want to wait as
long, you can download the sources from here.


since i had to make some substantial changes to the
"inner logic" of the plugin, please give it a try and let me know,
if there are any problems.
