Adding Legacy Tiles procedural (#1413)

Legacy Tiles added.

Supports all features from the Protein Tiles except the Column Modifier, which works only under specific conditions and mostly corrupts the pattern. I left it out. It's very unlikely anybody used it, ever.

Also fixing a couple of uninitialized inputs on Fractal Noise.
