User: optimise names/avatars storing and updating

The current mechanism relied on a complicated and fragile machinery
around setNameForRoom() and setAvatarForRoom() that maintained the
"most used" entity for a given user along with "other" ones. Given that
per-room avatars are pretty rare in Matrix, it's also been inefficient
as commit c69f100e shows. The new mechanism stores the "default" (as
per user profile) name and avatar and maintains a singleton map of
avatar objects across all users. Per-user profile only (normally) exists
for the local user so there's yet another inefficiency - this will be
fixed in 0.7 by introducing a special class for a user profile.
