Don't send invalid CHANINFO commands when no key is set

Browse Source 
It can happen that a channel is +k, but no key is set: for example by
misconfiguring a pre-defined channel. In this case, ngIRCd sent an
invalud CHANINFO command ("CHANINFO #test +Pk  0 :'", note the unset
key represented by the two spaces) to its peers.

Fix this and enhance the CHANINFO documentation.

CHANINFO is used by servers to inform each other about a channel:
its modes, channel key, user limits and its topic.
.
Note: even when <modes> don't include "k" (key) or "l" (limit), both
parameters must be given when used; use "*" for "no key" and 0 for
"no limit" for the unused parameter in this case.
.
The CHANINFO command is allowed on server-links only.
