Breaking changes from 1.x:

• Vue 1.x is not supported anymore, use vue-clickaway@1.0 instead.
• Submodules vue-clickaway/directive and vue-clickaway/mixin were removed. import the bits you want or require the whole module instead.
• Prior to Vue 2.0, directives used to be able to accept statements, like a++ or doSomething(context). This is no longer supported. Pass a method to the directive instead.
