Color Bar: fixes bug where if you reopen the colorBar tool window a 2nd time on the same band which itself is still open,  the title doesn't load.  This was a minor conflict with how the color bar layer aspect is sharing the same code.  The resolution is a few lines of code but essentially seems like a new feature.  Now if the user saves a color bar file or creates a color bar layer, the user settings are preserved in the ProductSceneView.  Once the band's window is closed then the settings go away.  To get these setting more permanently preserved we could consider moving the ColorBarParamInfo into ImageInfo and even into the dimap saving file.   Also I've created the start/stub of a new Color Bar Help page
