Allow customising of Content

[SirRawlins]

As part of the core product, we allow people to personalise the content on their status page, either by switching language or by using the "content" section from within the UI.

I'd like to add similar functionality to the plugin. However, I need to give some consideration as to the best approach for this.

My current thoughts are around a few different options:

1. Provide data- attributes on the plugin definition which allow users to ad-hoc their own content.
2. Provide locale.json files for the plugin with a bunch of supported languages.
3. Provide a JS object configuration option similar to data-which allows you to add or personalize languages.
4. Pull language/content settings down through the API (not yet supported)

All of these have pros and cons, if anyone has any thoughts or opinions let me know.
