Debugger: add support for executable file refs

Adds support for handling executable files in the
Debugger::RefsReceived function.

This change
* makes Deskbar menu->Recent Applications->Debugger->A recently opened
  executable open the executable instead of simply opening the
  Teams window, and
* allows dragging and dropping an executable onto the application's
  icon.
