Upadates all composer dependencies including the drupal core code as well as modules.

Prior starting the upgrade process a backup of the drupal-cdm-dataportal installation 

is created in $HOME/drupal-cdm-dataportal-backups/.

Some files in ./web/ which may be modified for specific setups are preserved during the 

update process:

 * web/.haccess*

 * web/robots*.txt

 * all symbolic links except for web/polyfills as this is managed through composer.  

USAGE: update-dependencies.sh [--deactivate-install] [--multi-site] [--mailto <ADDRESS>]

  --deactivate-install :  The install.php will be hidden by appending '.off' to the filename

  -h, --help:  Print this help text    

  --mailto <ADDRESS>:  send a email to the ADDRESS with a log of the update process

  --multi-site:  Do a multi-site update. Requires dataportals-drush. See https://dev.e-taxonomy.eu/svn/trunk/server-scripts/dataportal-admin/

  --site-url:  The site url to be used with drush. This option disables the --multi-site option
