The ClearBindHost and ClearUserBindHost success messages do not make a distinction on whether it's a network bind host that's being cleared or whether it's a user bind host that's being cleared.  I think that this should be reworded to make the distinction.

The CChan constructor makes sure that the channel name begins with a valid
channel prefix. Thus, this could change the name of the resulting channel.

When you edited an irc network which already had a channel "#foo", were
connected to IRC (so ZNC knows which prefixes are valid) and added a channel
"foo", this would lead to a problem:

Webadmin checks and sees that there is no channel "foo" yet. Webadmin creates a
new CChan instance for "foo". The CChan constructor notices that "f" is not a
valid channel prefix and instead calls itself "#foo". Then,
CIRCNetwork::AddChan() would see that this channel already exists, delete the
given channel and return false.

However, webadmin didn't check this result and would continue changing settings
on an already destroyed CChan instance.

Fix this by checking if the channel exists after CChan had its chance to mess
with the channel name. Also handle failures from CIRCNetwork::AddChan().

Fixes #528.

It confuses people too much.
Who wants ZNC to listen on localhost, may change settings immediately
after, via webadmin or /msg *status

Apparently StarChat.net uses a very old (?) or obscure NickServ
service that doesn't send any of the more common prompts for ID.
(It also doesn't support nick grouping, more's the pity.)

It's good for cross-compilation, because in that case binaries produced
