Title: 2.x - Expandable rows and actions column

Added ability to expand rows using an actions column in the grid
Actions column contains an edit, delete and expand button
Each of the buttons can be hidden or disabled
Able to supply callbacks for the edit and delete buttons so you can handle functionality in your application
HTML template that shows in the expandable div can be defined inside your ng-grid directive, and has access to the row entity
