* Change the read method of the config of the module.Developers can now easily read the config file in cmake.

e.g. AC_ADD_CONFIG_FILE("${CMAKE_CURRENT_LIST_DIR}/conf/my_first_module.conf.dist")

* Update Master.h

* Update cs_reload.cpp

Command: `.reload config` can now reload the config file of all modules #981
