When I run the navigator on IE10, there is an error in the InputCompletion.
Specifically at line 333, datalist is undefined so the loop below fails.

InputCompletion.prototype._proposeOnList = function(datalist, searchTerm, filterForMe){
		var categoryName = "";
		var categoryList = [];
		var searchTermLen = searchTerm ? searchTerm.length : 0;
		for(var i=0; i < datalist.length; i++){

fixed with http://git.eclipse.org/c/orion/org.eclipse.orion.client.git/commit/?id=2308d25116c26ade6186c79b25efb332882aed6e.

The reason is that IE10 kicks the "input" event before "focus" event on a text field. We initialize the inputCompletion._dataList on focus event but input event handler tries to use it before hand.
The solution is to init the this._dataList in the constructor as []. So that when ever input event comes first it will just pass it to focus handler.
