DataModel.query bug in FF

[jdgrieco]

I'm using Grid.dataModel.query with a RegExp object but in FF this doesn't work properly. While I debug this method I note: typeof spec[col] returns 'function' in FF

That's an interesting one. That check was added to avoid problems with people who have overridden the Object prototype. If you haven't, you can safely remove it.

I commented it out in my dev copy and added a note to the documentation that it may fail if you have overridden Object.prototype.
