Move FAQ 176 to s2howto tutorial

I'd like to move FAQ 176 to an s2howto tutorial. It's very complicated for a FAQ and though I'm not sure on the usage of that particular fact, it seems like it doesn't really "fit" with the rest of the FAQs in the Customization categories. Here's the text:

Makes sense to me. We don't generally reference FAQ 176 (or even 177) in requests anyway, probably because it's more complex and requests of that type fall into the "!pony" category.

while you're at it, can we add a simple, friendly FAQ on creating a theme layer? that is one howto I referenced so ridiculously frequently that I feel that it really should be a FAQ... and always meant to make it one. :p
