Added support for 'password' parameter type
Added support for file input fields (https://github.com/mashery/iodocs/issues/1).  The assumption made in this implementation is that the API request is expecting any files posted to the request to be named the same as the input field.  As long as that is true, you can add as many file input fields as you like to a single method as long as they have unique names.  To keep things simple, I replaced the existing use of the built-in http/https module with restler (https://github.com/danwrong/Restler/), which elegantly handles multi-part form encoding.
Fixed bug preventing the API key input field from showing up
Added ability to load api definitions via HTTP(S). Add the key apiDefURL to the apiconfig.json definition, and at page load the contents of the given URL will be parsed to JSON.
Updated documentation
