Many improvements on IRC raw buffer

New features:
- key alt-j alt-r is reintroduced to open IRC raw buffer
- command "/server raw" opens IRC raw buffer
- new option irc.look.raw_messages, which is number of lines to keep in memory
to display when user will open raw buffer (to see last messages received before
opening raw buffer)
