Improve op user rendering in member list

[raucao]

Currently, they just have an @ in front of their name, because that's plain IRC. Should remove the @ and add a status to the user object, as well as highlight it visually somehow.

Related: it looks like there's a bug in the current master when trying to message an op by clicking their name in the channel list. Since the username is prefixed with @ it does not work:

  sockethub-platform-irc Unprocessed message [irc://hyper_greg@irc.freenode.net]:  IRCMessage {
  prefix: 'cherryh.freenode.net',
  command: 'ERR_NOSUCHCHANNEL',
  params: [ 'hyper_greg', '@ChanServ', 'No such channel' ],
  server: 'cherryh.freenode.net',
  raw: ':cherryh.freenode.net 403 hyper_greg @ChanServ :No such channel',

@gregkare That would be a different issue. Care to create one specifically for that bug?

Will do!
