Remove old "get_elsa" googlecode portion of install.sh

[NoX1De]

Would it be safe to remove this now from install.sh with the google code repository no longer existing:

get_elsa(){
    # Find our current md5
    BEFORE_MD5=$($MD5SUM $SELF | cut -f1 -d\ )
    echo "Current MD5: $BEFORE_MD5"
    # Get the latest code from Google Code
    cd $BASE_DIR
    # Check to see if svn accepts --trust-server-cert
    SVN_TRUST_SERVER_CERT=" --trust-server-cert"
    svn help export | grep trust
    if [ $? -ne 0 ]; then 
        SVN_TRUST_SERVER_CERT=""
    fi
    svn -r $VERSION --non-interactive $SVN_TRUST_SERVER_CERT --force export "https://enterprise-log-search-and-archive.googlecode.com/svn/branches/elsa/1.5" elsa &&
    mkdir -p "$BASE_DIR/elsa/node/tmp/locks" && 
    touch "$BASE_DIR/elsa/node/tmp/locks/directory"
    touch "$BASE_DIR/elsa/node/tmp/locks/query"
    UPDATE_OK=$?

    DOWNLOADED="$BASE_DIR/elsa/contrib/$THIS_FILE"
    AFTER_MD5=$($MD5SUM $DOWNLOADED | cut -f1 -d\ )
    echo "Latest MD5: $AFTER_MD5"

    if [ "$BEFORE_MD5" != "$AFTER_MD5" ] && [ "$USE_LOCAL_INSTALL" != "1" ]; then
        echo "Restarting with updated install.sh..."
        echo "$SHELL $DOWNLOADED $INSTALL $OP"
        $SHELL $DOWNLOADED $INSTALL $OP;
        exit;
    else
        return $UPDATE_OK
    fi
}
