Sprite Buffer update

I was wrote a script (Sprite Buffer) by user request to add in 3ds Max frame buffer feature similar to existing in Maya. I don't plan to extend or update this script, but today David Svantner send me him modified version of my script which add Autoappend function using postRenderFrame callbacks to can easily render animated sprite sequences. I attached it right now as is to be available for downloads, but when i've got more free time will modify it to work with checkButton instead of popup dialog for convenience with turn on/off Autoappend.
