Auto-size column should consider width of aggregate columns

Currently the aggregate columns are not considered when you have auto sized columns. This usually will force a scrollbar which in many cases is undesirable. 
In my use case, I hide the column being grouped by (e.g. grouping by 'date' hides the 'date' column), but even though I have a few auto columns when I group by it goes passed the width I set. Forcing an ugly scroll when there are only a few columns.
CsvExport: customize link label, class, filename

Extending opts argument so its possible to customize the filename, link label e css class.
Improved keyboard navigation

Modified the keyboard navigation selection handler to account for not
only invisible columns but also columns with a width of zero. This allow
better in grid validation when using ng-form attributes

change line from
var value = item[condition.column] || item[col.field.split('.')[0]];
to:

Exporting custom headers

When exporting a column that uses the displayName property the csv export
will use that property to populate the column header.  If it doesn't have
a displayName set it will just use the field property like normal.
