Houdini -> Magic Voxel exporter

[symek]

Hi Mykola, how are you? Some time ago I've added this buggy snippet to your code ;), but then forgot about it. I'm not sure what state it is now, but for a record I pull request it to you. It was tested on Linux. I think there is a bug in pallete code, but at this point I'm not sure what it was (sorry for that). I might look into it if anyone interested.

Some folks here are playing with MagicaVoxel so I've excavated repo for them.

Greetings! Szymon.
