#1983774 - start script passes parameters incorrectly

When you launch [ganttproject.sh "my file.gan"] on the command line the
bash variable $1 is "my file.gan" while the ganttproject.sh script runs,
but the java app tries to open "my" instead of "my files.gan".

This is due to a bug in the ganttproject.sh script:
$JAVA_COMMAND -Xmx256m -classpath $CLASSPATH:$LOCAL_CLASSPATH $BOOT_CLASS
$CONFIGURATION_FILE $* >$GP_HOME/ganttproject.log 2>&1

Passing parameters with the $* does not preserve the spaces and blanks and
one parameter becomes two or more if there was a space in it. If one wants
to preserve those blanks the "$@" formula needs to be used. So the correct
line is:
$JAVA_COMMAND -Xmx256m -classpath $CLASSPATH:$LOCAL_CLASSPATH $BOOT_CLASS
$CONFIGURATION_FILE "$@" >$GP_HOME/ganttproject.log 2>&1
