New release v1.3 of McStas

[Kristian Nielsen]

I am pleased to announce that McStas v1.3 has been released and may be
downloaded from the web site:

    http://neutron.risoe.dk/mcstas/

Major new features include a new McDoc component documentation system
which among other things provides nice graphical dialogs for building
instruments, a much improved `mcrun' front-end, multiple scattering in
the Single_crystal component, and more. See the CHANGES file in the
distribution for details on what is new in v1.3.

All McStas users are encouraged to upgrade to the new version. As usual,
please report any problems so that they may be fixed in a later version.

 - Kristian.
