Move document.ready() functionality to separate function

[x4v13r64]

This is a small PR, all it does is move the content of $(document).ready() to a separate function. It also moves hidePleaseWait() to the end of load_metadata().

This is required for the managed service, because the JSON/JS is loaded asynchronously, so we need to call the content of $(document).ready() once the JS has been loaded.
