Исправлена ошибка, приводящая к невозможности синтеза проекта (файл hazard_unit.v).

Файл test.asm был скорректирован (код теперь соответствует комментариям).

Был добавлен скрипт convert.py, генерирующий файлы инициализации для памяти.

Для сборки спомощью makefile теперь необходимо установить python версии 2.7+ (наличие perl больше не требуется)
