Add-ons s9e Media Sites 2.15.5

• Dark theme should be functional again on XF 2.3 with embeds that support it.

• Added On3 DB Industry Comparison widgets.
• Updated 247Sports player stats embed. Their video player cannot be embedded anymore and has been disabled.

• This update fixes an issue with XenForo 2.3 that causes embeds to be loaded eagerly (rather than lazily) if the user is an administrator and template names debugging is enabled.
• Also, somehow Palpatine returned Bleacher Report was still present in last update. It's now been properly removed.
