New Tool (3.0): Midi Convert

[joule]

3.5 had some trouble running this, but it was easy to fix by just putting local arg = {…} at the top of two functions (process slicer). I guess quite a bunch of tools are in need of the same tweak.

arg: LuaJIT does not set the magic arg varargs variable, which already was deprected in Lua 5.1. Replace it with local arg = {...} instead. See lua arg vs {...} on stackoverflow
