Speedup playlist population

[Speedvicio]

As specified on title request ,can you speedup the playlist population removing any control that rePlayer perform on every single file? If you can, you could add a option in settings to let the user choose if perform this controls or not.

Playlist should be populated very quickly as the only "control" performed is the extension check; the remaining checks are done asynchronously and are not blocking anything. But it can be slow in the win32 version on a poor system because of the mutli-threading.
