/**
 * Some (proposed) option naming conventions:
 * - Starts with a general identifier
 *   General_ for, well, general things =)
 *   Server_ for webinterface specific things
 *   GUI_ (eventually) for GUI specific things
 *   Core_ (eventually) for core specific things
 * - Second is some identifing term. It starts with a small letter denoting
 *   the variable type.
 *   b Boolean
 *   i Integer
 *   s String
 * - Directory options should end with _Directory. This activates some
 *   special validity checks in the webinterface option parsing code.
 *   (Namely they are created if they don't exist and the option isn't changed
 *   with a logged error if a normal file of the same name exists)
