Duplicate arrow icons top and bottom

[pllim]

With the latest dev version of Ginga, I see left, right, up, and down arrows both on top and at the bottom of the display (but ordered differently). Do you have plans to remove the bottom ones? It seems confusing to have two sets that do the same thing.

Don't think it matters, but my machine is Linux and I am using Qt4.

@pllim, After examining the new workspace toolbar do you think you would enable it in stginga (see the layout in main for the correct keyword parameter to the workspace)? I'm thinking of whether to just remove them from the bottom toolbar, or to make it configurable.

In our case, I think we have two configurations that would use the new toolbar and one that probably would not.

@ejeschke , for my project which uses only one channel, the new workspace toolbar is not that useful. But I can see how it can be for a different workflow. Regardless, having duplicate icons (especially in different ordering) can be confusing.
