dojox.grid hidden column doesn't work in Chrome and Safari

[niofox]

The hidden columns in grid does not work in Chrome and Safari latest versions.

The bug is solved by changing in the file _Grid.js the following code lines from:

if(d.hasAttr(th, "hidden")){
    cell.hidden = d.attr(th, "hidden") == "true";
}

To:

if(d.hasAttr(th, "hidden")){
    cell.hidden = (d.attr(th,"hidden")=="true" || d.attr(th,"hidden")==true);
}
