SantaGUI headline not centered and ugly

[tburgin]

Looks like this takes place with the commit a2a660d. Dropping this commit fixes the issue.
Something doesn't like the use of modules I guess.

Eww.

When clicking on the text it turns black?

Re-adding a pch for just SantaGUI fixes the issue 😕

This is caused by this ifdef, which exists because NSAttributedString's initWithHTML:documentAttributes method is defined in an AppKit extension (NSAttributedStringUIFoundationAdditions in UIFoundation.framework) and SNTBlockMessage is common code - the ifdef worked because of the way PCH's worked vs modules.

I'm sure there's an easy way we can check that AppKit is available that still works for modules.

Fixed with #161
