baptr 90a5f23e79 Fix editor profiler script function sort order
The engine internally limits the number of functions reported back (to
16 by default). To this point, it's been sort the profiling info in
*ascending* order of time spent, then trimming the list. This meant
we may only see the best (fastest) functions, instead of the worst
that you probably want when profiling.

Now the servers_debugger sort more closely matches the local_debugger
one, which worked fine.
