Pass fanclub links from endpoint to template contexts

[pushred]

The sparkart-services fanclub endpoint provides an array of helpful links for a site's primary URL, any setup forums, etc. Sparkart.js doesn't pass the contents of this endpoint on as-is however, presumably to not pass along things like status. This simple update provides these links to templates for rendering and durable integration rather than horrible hardcoding.

Just need to standardize our tabs vs spaces. Code looks good.
