DONT MERGE Add carrierwave

@syoder ,
I just can't figure out what I am doing wrong with the pictures. When a report is created, the picture should be saved to the database, but something isn't set right, so the :picture parameter is either being blocked or the ```@report.picture.create(picture: picture)``` is not working.

Care to take a look?
where is `picture` coming from?  shouldn't that be `@report.pictures.create(picture: params[:picture])`?

A better way to do this might be to use `accepts_nested_attributes_for` in the model.  Then add a `fields_for :pictures` in the view.  And there is some magic you have to add to the controller to permit the `pictures` param.
