MAJOR CHANGE TO THE STRUCTURE OF THE ISISscripts:

From now on, the files share/isisscripts.{sl,txt} are not part of the
isisscripts anymore. This has major implications:

1) Hence, if you want to load the isisscripts from this git
   repository, you have to run 'make' after any changes were pulled.
   If you forget this step, you might run into troubles of using a old
   version of the scripts _although_ the git is up-to-date.

2) The other option of obtaining the isisscripts is to copy them from
   http://www.sternwarte.uni-erlangen.de/isis/. Every successful
   commit to the scripts will be uploaded immediately. Hence, if you
   are only using the scripts with the intention to edit them, you can
   also stay up-to-date by a simple wget job scheduled with (a)cron.
   This webpage also contains more information on the ISISscripts.

3) Contributing to the scripts works as usual (see the README file).
   As the share/isisscripts.{sl,txt} have been added to .gitignore,
   these files won't be commited any more automatically. Hence,
   running 'make' is not necessary for a successful commit. But you
   will still have to run it in order to test your changes before
   pushing them.

4) In case your change breaks the repository, you will be directly
   informed by eMail. So, please check and update your eMail with
   git-config (how to do it? google is your friend :-) ). Note that
   now broken commits will be uploaded on the homepage.
