Refactor: Created factories and controllers

I refactored the code to break the data out into factories and created
individual controllers for samples that required a controller. Some
samples I removed the controller from the markup as it was unnecessary.

Updated igniteui-angular.js to handle feat events

Before this update as a directive is being processed (extractOptions
function) the grid feature events that were being subscribed to were
missing the full name of the event - thus never really subscribing the
event.

This fix ensures that the fully-qualified event name is used to setup an
event handler.
