Fixed a bug where using a parameterless cellFilter would stop the grid filtering from working. Example Plunker: plnkr.co/edit/nL1dvjMAnuvHdHPgGv9L
Fixed a bug where the filtering stops working if one of the fields in the columnDefs is pointing to an object
Mixing semicolon from previous commit
Added russian translation
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
Fixed mixed spaces and tabs
Fixed tabs issue.
fixed retrieving value for group header from booleans
when sorting a column with booleans false is treated as null
Grid error on $destroy

Check to make sure that the grid.$root is not undefined when removing
DOM elements
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.
Support for maxHeight

With the current state of this plugin, was not posible make the grid flexible with a maxHeight while adding rows dynamically.
Update ng-grid-flexible-height.js
quick fix for issue #1202

#1202
after resize column + http.get causes all column missing (col.width = NaN)

has bug for resize event causing NaN for all column width after another http.get
Update ng-grid-reorderable.js
Update grid.js

Added minimal width rule for asterisks
Improve the performance of the CSV export plugin.

The previous version of the plugin scanned the entire csvData set
when replacing the last comma with a newline. This is a huge
performance hit for large datasets.

This version only scans the current row to replace the comma with
a newline.
Fix to get ngGridReorderable working again

Fixes a few broken references and gets the drag and drop action working again.

I'm unclear if the indexes in the rowCache should be updated to match the new row positions, but the display does update correctly.
