Use >!< where possible

[fsommar]

mkBoxOf(new Message(some, arguments)) { packed =>
  implicit val acc = packed.access
  sender ! packed.box
}

has now been mostly superseded by >!<. However, it's only used in these types of fire-and-forget scenarios, and as soon as the user requires more expressiveness they have to fall back to the previous version. The above send would look like the following, using >!<:

sender >!< new Message(some, arguments)

Clearly a large win in convenience!
