lua consolidate playlist_ functions

Browse source 
The way to call the playlist functions has changed
rb.playlist("option", var)
rb.playlist_add(filename) = becomes rb.playlist("add", filename)

added playlist.lua to the includes for conversion to old functions
if your script is broken by this change you simply add `require("playlist")`
to the top for the old functionality

added rb.playlist_tracks(dir, filename) to playlist.lua
this will allow you to add all tracks in a playlist.m3u8
to a lua table
