[Feature request] Make KVM switch channel labels customizable

[mluna0101]

In the web interface it would be nice to be able to change the channel button labels to something that makes sense to what is connected to the port instead of just channel numbers.

Say, Channel 1 could be renamed to something like "Main server", Channel 2 to "NAS", Channel 3 to "Hypervisor" and Channel 4 to "Linux".

Maybe it doesn't look too useful but when you escalate it to 8 channels or more then you'll really appreciate that feature, especially if you don't access the KVM that often.

That's a good suggestion, we will add this feature in future versions.
