--User changes

-Add Summary tab to the info dock, place existing bounds related info in a new Bounds tab.
 -Add a toolbar with the most common actions on it.
 -Remove old toolbar at the top of the library tab.

--Code changes
 -Refactor code to make a color visible on a background into VisibleColor() in FractoriumCommon.h
 -Add IsXformLinked() to determine if an xform is linked to another.
 -Remove SetPaletteRefTable() and GetQRgbFromPaletteIndex() from FractoriumEmberControllerBase and its derivations, unused.
 -Add FillSummary() to FractoriumEmberController. Call in Update(), UpdateXform() and other places where values are changed to force an update of the summary view.
 -Add export statements to FractoriumInfo.cpp.
 -Remove image parameter from SetPaletteTableItem(), it was a bad design.
 -InitToolbarUI() is now empty since toolbar initialization happens automatically. Leave as a placeholder.
 -Refactor code to get a palette color at a given index and convert it to a QColor to ColorIndexToQColor().
