Log message:

	* ircd/gline.c: detect overlapping G-lines; if an existing, wider
	gline expires after the new one will, we drop the new one,
	otherwise we add the G-line after that one (so the wide one will
	apply first); if the new one contains an existing G-line and if it
	will expire after the existing one, we drop the existing one to
	save memory

	* ircd/m_gline.c (mo_gline): opers could issue remote local
	glines when CONFIG_OPERCMDS was off; fixed
