Subject: github-url: Move functions into `autoload`

Improve performance by eliminating the functions from the `plugin` file.

Also introduces a new `github_url#GitHubURL()` function that serves as
an entry point into the plugin.

Add a `g:loaded_github_url` check to prevent plugin re-sourcing and be a
good Vim citizen.
