Implemented automatic plugin instantiation on containers

* Added check for the instance object to avoid errors when the data-input-navigatino properly is not ser correctly on the container
* Added support for automatic detection of the data-input-navigation attribute on forms
* Moved ‘use strict’ outside of the function call (and added a rule on jshint to expect this)
* Added a better way for type checking
Adding ready.input-navigation.data-api method
Eliminating custom ‘toType’ method in favor of instanceof
