TOOLS: add a Lua script to autoload playlist entries
This will load other files in the same directory when a single file is played. It's an often requested feature, but we definitely don't want it in the core.

+-- This script automatically loads playlist entries before and after the
+-- the currently played file. It does so by scanning the directory a file is
+-- located in when starting playback. It sorts the directory entries
+-- alphabetically, and adds entries before and after the current file to
+-- the internal playlist. (It stops if the it would add an already existing
+-- playlist entry at the same position - this makes it "stable".)
+-- Add at most 5 * 2 files when starting a file (before + after).
