Начал работу над текстовым представлением +
редактором журнала.
Пока что в textarea выводится текстовое представление.

Редактировать можно, но сохранять пока нельзя.

Пытался сделать автоматическое позиционирование курсора
на нужную строку.
Во-первых, не работает в Konqueror и с этим, я так понимаю,
ничего пока сделать нельзя.

Во-вторых, неверно вычисляется строка на которую нужно
позиционировать курсор.

Это, я думаю, можно подправить.

Потом, что-то намутил с utf8. Надо будет более детально
это рассмотреть
