Merge #61

61: Instructions for the stdweb backend in the hello example. r=grovesNL a=theypsilon

Previously there weren't instructions to run the 'hello' example on stdweb, so I'm adding them.

But I also noticed that the README.md is not quite right yet. The web-sys backend instructions seem obsolete, but I can't find and easy way to make it work with wasm-pack because 'hello' is a binary crate.

Here is a pull request to make wasm-pack compatible with binary crates: rustwasm/wasm-pack#736
