v2.0.0

Features

• callback should return instance not class (c3c7b87)
• follow standard jQuery praxsis for 'this' (42997c8)
• remove .find from $.fn.wire and instead rely on 'this' (82d5f56)

BREAKING CHANGES

• Users have to $(element) on their own in callback.
• Callback now has to return an instance not a module.
• users will have to update their code to first select
  elements. A simple way to do this is by adding .find('[attr_goes_here]')
  right before the .wire call.
