* 02.06.2009 Calculate Pack http://www.calculate-linux.org
*
* В исходный код calcreadconfig.c внесены следующие изменения:
* - если параметр .conf или .cfg, то это конфигурационный файл меню
* в остальных случаях параметры аккумулируются в дополнения для передачи
* далее
* - если параметре, значения которого перечислены через запятую возможна
* замена одного из значений (например переходящий параметр test=1,2,3
* test=,,6 заменит в этом параметре последнее занчение => test=1,2,6
* - добавлены функции разбивки и объединения строки
