Commit e2e450f9 started making use of luaL_register(), but OF COURSE
this function disappeared in Lua 5.2, and was replaced with a 5.2-only
alternative, slightly different mechanism.
So just NIH our own function. This is actually slightly more correct,
since it forces the user to call "require" to actually make the module
visible for builtin C-only modules other than "mp". Fix autoload.lua
accordingly.

-- 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".)
