Title: Added which utility to find pre-installed version of optipng

When trying to use yeoman on webfaction shared servers (CentOS) where I do not have permissions for global installs and src builds, I needed a method to point to the pre installed binary. With this change, I can run:

```$ npm install```

and it will use the optipng binary located at:

``` $HOME/bin/optipng ```
