/**
* @class Ext.ux.grid.RowActions
* @extends Ext.util.Observable
*
* RowActions plugin for Ext grid. Contains renderer for icons and fires events when an icon is clicked.
* CSS rules from Ext.ux.RowActions.css are mandatory
*
* Important general information: Actions are identified by iconCls. Wherever an <i>action</i>
* is referenced (event argument, callback argument), the iconCls of clicked icon is used.
* In other words, action identifier === iconCls.
