Keep repeat payload focus when switching between GUI & XML views

[apizz]

For payloads that support multiple payloads of the same type (ex. Wi-Fi), additional payload tabs appear. However, when switching between GUI & XML views, the first payload is always selected. Would like PC to keep the selected payload in focus when switching between GUI & XML views.

A description of what happens currently:

1. With multiple payloads created, select any payload except the first in the GUI builder.
   
2. Click the XML view button.
3. XML view switches back to the first payload, rather than displaying the selected payload XML.
   
4. Select the desired payload in XML view.
5. Click the GUI builder button to switch back.
6. Once again, the first payload is selected.
