--hide option prevents commands from being responded to

[KoraggKnightWolf]

I normally invoke ircdog with the --hide=ping,pong switch in order to not have the screen get cluttered with PING and PONG output. However this leads to ircdog getting registration timeout errors when attempting to connect to networks, even when correctly formatted NICK and USER commands are sent. This does NOT occur when leaving out the --hide switch so it appears that --hide makes it so ircdog does not respond at to hidden commands. This becomes problematic as it no longer responds to PINGs in my case, and networks often send "ping cookies" on connect.

Steps to reproduce:

1. ./ircdog --tls --hide=ping,pong irc.snoonet.org 6697

2. send valid NICK and USER commands

3. Observe that the result is a registration timeout.

However without --hide=ping,pong it connects just fine

1. ./ircdog --tls irc.snoonet.org 6697

2. send valid NICK and USER commands

3. Observe that ircdog connects succesfully, seeing 001-005, the MOTD replies etc.
