- don't mix /instrumentation/radar and /instrumentation/wxradar wildly

together -- there's only *one* instrument node now
- don't take "random" tacan, but <tacan-source> from the instrumentation
  config (or /instrumentation/tacan[0] by default)
- don't take "random" display-controls from /instrumentation/tacan[0]
- default name is now "radar" (formerly "wxradar")
