Updating sshchat label
Remote nick formatting fixes
Remove some redundant linkages:
Remove commented out tg for #libcasa.info as it is not being utilised
Remove stale dota related bridge
Removed keytomb stuff as it is stale and didn't work anyway.
Reroute bridges:
Rerouting sshchat from #libcasa to #lucy as there isn't much conversation on #libcasa atm. So if it will be getting used, it's likely only to communicate on #lucy.
