Copy key/value/names ContextMenu for resource tables

[miloush]

Fixes #3023

Problem

The resource tables show document context menu that does not allow copying items.

Solution

This PR adds a context menu with a few copy options.

It also fixes the issue that the normal copy uses simple ToString() which

• for object table is not overloaded and just copies the internal ILSpy type name
• for string table it used [Key, Value] syntax

Now it separates the columns by tabs so that they can be pasted into Excel etc.

Small nit: having the same shortcut for three different menu commands seems a bit strange to me.

[christophwille]

Yes, only one Copy item should have the Ctrl+C shortcut.

[miloush]

Yeah only this first one has the shortcut actually. If you have a smart idea how to not show it for the others, let me know. Otherwise this needs to be much more complicated PR with new commands or templated MenuItem and it is not exactly the most prominent menu. Unless you are happy with something like InputGestureText=” “ that might work…?

Unless you are happy with something like InputGestureText=” “ that might work…?

That is the solution I was going to suggest. No need to over-complicate things :)

[miloush]

That did the trick indeed. I wonder whether we should fix this on WPF side...
