added: program reads its configuration from a config file

Browse Source 
added: confparser directory and confparser.h and confparser.cpp
       class ConfParser used to parse a config file
       this is a generic parser, can be used by another project
added: config.h, config.cpp
       class Config used for assigning values from 
       a config file into the data object
added: function for signals: SIGINT, SIGHUP
       after receiving SIGHUP the program will read
       its config file again
