Added 'base' and 'variables' to a CONF_SECTION, which are added

	Added 'base' and 'variables' to a CONF_SECTION, which are added
	by cf_section_parse.  Now, when someone calls cf_section_free(),
	the strings allocated from cf_section_parse() are automatically
	free'd, too.

	For now, we only do this for the base variables in mainconfig.
	If we enable this for all of the modules, we first have to
	update all of the modules to NOT explicitely call free() on
	the strings allocated by cf_section_parse().
