Subject: [PATCH] Test wxDynamicLibrary::ListLoaded() in debugrpt sample.

The list of loaded dynamic libraries gets included in the debug report, so it
seems logical to test this function independently in this sample to allow
checking whether it works correctly without having to generate a debug report
first.
