Allow IRC commands to not have parameters.

Browse source 
When testing against irc-dcc-send.trace, I didn't see an irc_quit_message event generated for the QUIT command at the end of the trace, but rather a weird.log "irc_invalid_line" for the packet: the IRC packet parser wasn't allowing commands without parameters.
