0.1.5

milo.util.request

• messaging support for jsonp and file requests.
• whenRequestsCompleted method to call callback when all requests are completed
  (or if there are no pending requests)
• tests

Drop facet

• dragin and dragout messages that only fire when mouse enters/leaves the component's element,
  ignoring enter/leave of child elements (dragenter and dragleave messages are still emitted as usual).
• all messages are re-emitted on drag-drop service (milo.util.dragDrop.service).

milo.minder

• whenPropagationCompleted method that calls passed callback when propagation is completed or
  when there is no data propagation. Using this function is better than subscription
  milo.minder.once('propagationcompleted', callback) because in the former case callback will always be called
  and in the latter only if there is propagation happening.
• isPropagating method that allows to determine if data propagation is currently happening.

Added mock for XMLHTTPRequest for testing.

Fixed memory leaks, added destroy methods (milo.destroy and others).
Calling milo.destroy() will make milo unusable, only useful inside iframe that has to be disposed of.
