Better !channel support - window items now have "visual_name" and channels

and queries also have "name". Normally they're identical but with !channels
the visible_name contains the short !channel name, while name contains
full !ABCDEchannel name.

The visible_name should be used whenever displaying the channel name, or as
printtext()'s target. So, this breaks a few scripts in !channels, they need
to be modified to use $channel->{visible_name} instead.

Also /LAYOUT SAVE should finally work properly with !channels.
