Title: Extend TreeGrid functionality to support icons assinged per node

Currently the icon property will be supported only for leafs. The property can contains CSS class which will be used instead of default `ui-icon-radio-off` class.

It will be suggested to allow to use icon property for non-leafs too. In the case the value should be *two* CSS classes devided by comma. The first class defines "minus icon" (expanded node) and the second class defines "plus icon" (collapsed node).

[The demo](http://www.ok-soft-gmbh.com/jqGrid/LocalAdjacencyTreeIcons.htm) demonstrate the modified version of TreeGrid. The original idea are described in [the answer](http://stackoverflow.com/a/9482049/315935).
