added: a new directory "etc"

there'll be some generic config files for winix
added: a new file in etc directory: time_zones_file
       list of time zones (not finished yet -- daylight saving time is needed)
added: option to config: etc_dir
       a directory in which there are some config files
       used mainly when winix starts
       default: empty (means not for using)
added: option to config: time_zones_file
       a file in etc_dir with time zones info
       default: time_zones.conf
       this is a Space structure with all time zones
added: to system: TimeZones struct
       list of time zones read from etc/time_zones.conf
