Make the "nodes" command clearer

Because literally anyone who isn't a dev has
no idea what those fucking numbers even mean...

Before:
$nodes
00 - Sonic - 01 - 666.66.420.42:5029
01 - Tales - 00 - self
02 - Nukes - 255
03 - Ammie - 255
04 - Fangs - 255
05 - Metal - 255

After:
$nodes
00 - Sonic - node 01 - 666.66.420.42:5029
01 - Tales - node 00 - self
02 - Nukes
03 - Ammie
04 - Fangs
05 - Metal
