Request: add Facebook to bots list

Hi there, we’ve had trouble with WP Splash blocking the Facebook crawler so that when people share links they get the content of the age gate rather than the page.

I fixed this by adding two bots to your $spiders list in class-wp-splash-page.php:

‘Facebot’, ‘facebookexternalhit’

Any chance you can add this to the official version of the plugin so that updates don’t break access for Facebook? I would have thought this will be useful for anyone using your plugin.
