A bunch of bug fix

[etiennepouliot]

If you define your Datatable with exclude instead of columns :

class FooDatatable(Datatable):              
    class Meta:                                      
        exclude = ['id']                             
        processors = {                               
            'env': helpers.make_xeditable,           
        }      

It will trigger HttpResponseBadRequest("Invalid field name")

This check both columns and exclude.

I would love to use this but with the number of conflicts and no tests its going to be a challenge? How do you want to proceed?
