Index grid improvements about crud-view

[josegonzalez]

I've opened up specific issues for everything so we can start working on them one by one :)

Maybe you would consider a new one already! :-)

The "Copy" Action.

One press the copy action button (index page) row of register "{id:2,name:'paul',age:'10'}" and the add form is shown with those values already filled.

Sounds like a new action that would need to be set in Crud and then have CrudView integration. Can you open an issue in Crud for that?
