Subject: [w3m-dev 03578] meta refresh * file.c (getMetaRefreshParam): do
 nothing if refresh_interval < 0 	(HTMLtagproc1): rewrite refresh 
 (HTMLlineproc2body): add HTML_META * fm.h (BP_RELOAD): deleted 
 (Buffer): add event 	(AL_IMPLICIT_DONE): deleted 	(AL_ONCE): deleted 
 (AL_RESTORE): deleted 	(AlarmEvent): added * main.c (AlarmEvent): deleted 
 (PrevAlarm): deleted 	(DefaultAlarm): added 	(CurrentAlarm): point to
 DefaultAlarm 	(main): CurrentKeyData, CurrentCmdData 		handle
 Currentbuf->event 	(SigAlarm): CurrentAlarm is pointer 
 (copyAlarmEvent): deleted 	(setAlarm): setAlarmEvent pass &DefaultAlarm 
 (setAlarmEvent): arg event 	(ldDL): no BP_RELOAD * proto.h
