Подправлен скрипт l3bashrc.
Теперь определение запущен ли скрипт на текущем терминале или нет,
выполняется через PPID
Идентификатор сессии изменён.
Теперь это просто 8байтоное случайное число + время начала сессии.

l3scripts:
Вместо процедуры инсталляции lm-install
мы теперь просто копируем l3bashrc в lilalo и всё
