Create binarySTL-LoaderSource.js

contains a binary STL loader on line 234. Somebody more capable than I am might be able to trim this down to just the binary STL loader portion so we can add it to the three.js loaders. This code actually contains three different loaders: ascii STL, binary STL, and OBJ.
