added profile statuses

Adds the link reltype 'adds-status' which is structured like this:
```js
{
$rel: 'adds-status', // required
$feed: <hash>, // required
text: 'status text', // required
textColor: <hex_value>,
duration: <lifetime_in_ms>
}
```

Statuses allow messages to pin colored text (and, someday, icons/images) to somebody's profile. This can be used to cast spells, equip hats, and generally just goof around.
