Entity Info Box

Typically on hovering an user or a group's photo/nickname in a notice list, it will show show advisory info and actions to take. The following are some candidates (we should keep it lean):

entity_profile
 * photo
 * nickname
 * fn
 * location
 * url (may be excess info but it is probably useful)
 * bio
 * tags (may be excess info but it is probably useful)
 * Stats (probably just subscriptions, subscribers numbers) and link to those pages
 * User subscription type: whether it is bidrectional or oneway
 * Common Connections: This is more of a feature in and of itself. I think it might be good to show a short list of common subscriptions to give the viewer an idea. Probably should be implemented at a later date.
 * Indicators: If the user is a featured user, or have a user role assigned, show an indicator

entity_actions
 * Subscribe/Unsubscribe or Join/Leave
 * Message
 * Block
 * Flag

Approach

 * Do a single GET per profile
 * Use  (or  ) to GET the profile URL data (e.g., http://identi.ca/csarven#i would target the entity_profile), or;
 * A little tricky because we might have to disable or find a workaround for the clickjacking prevention script, otherwise, it will redirect. It also GETs the full URL content. The benefit is that, it grabs remote profile URLs easily.
 * Use an XHR
 * Probably the best way to go at this. Minimizes XHR response's Content-length and can be customized. Would probably need to use Curl to GET the remote profile.
