[Debugger] Updated ObjectValueTree to use Edit icon instead of Zoom icon
[Ide] Added Preview(eye) icons used in Debugger ObjectTreeView as preview button
[Debugger] Fixed ObjectValueTree GetCellAtPos method
GetCellAtPos method was not returning correct result in case column had Expander arrows
Result was offseted by tree depth * 16px(aprox. space used by expander arrow)
[Debugger] Initial commit for PreviewVisualizers(partial Size and Color)
