* changed the behaviour of the config file:
  - now all the config options are saved. <string> config options which have
  no default value are also saved in the config file but as an empty string.
  - config_LoadConfigFile will ignore empty config options, which also means
  we cannot pass an empty string as a <string> config option. (this shouldn't
  matter anyway)
