* @class LLPanelInventoryListItemBase
*
* Base class for Inventory flat list item. Panel consists of inventory icon
* and inventory item name.
* This class is able to display widgets(buttons) on left(before icon) and right(after text-box) sides
* of panel.
*
* How to use (see LLPanelClothingListItem for example):
* - implement init() to build panel from xml
* - create new xml file, fill it with widgets you want to dynamically show/hide/reshape on left/right sides
* - redefine postBuild()(call base implementation) and add needed widgets to needed sides,
*
