* The Add{String,Integer,Boolean} functions will allow you to add multiple
  entries with the same variable name (idname). You shouldn't do this, since
  only the first one will be saved. The reverse is also true - If there is
  multiple entries in the configuration file with the same variable name
  (idname), it will all be parsed. It is your responsibility to check whether
  there is multiple entries of the same name and to remove the unnecessary
  ones or to give an error.
