Optimize component chooser startup time more 

- Stop wx from sorting the items. We've already sorted them, and
  profiling shows our sort is faster than theirs.

- Go back to using strings as cache keys, because using pointers means
  the cache doesn't survive from one invocation to the next. Switch to
  wxHashMap because it can use wxString keys in an unordered (faster)
  map.
