Add an option to highlight the selected node (listener / pipe) in the code editor

[philipsens]

The Flow MVP had this too. But think we can one-up it this time!

It would be really useful to have an option in the node context menu to jump to the adapter in the xml. The option could be called "jump to code", "highlight in xml", "show in xml" or "open in editor".

It would also be useful to have a shortcut too.
