Title: Adding Stack Exchange-style spoiler tags

Over on Stack Exchange, they implemented spoiler tags this way:

>! spoiler!

Which would get rendered as:

spoiler!

Built-in spoiler markdown is a popular request on reddit, and I think this'll make spoilers much nicer to use on reddit (especially on mobile). This won't support inline spoilers, though; some other syntax will need to be implemented.

In a commit to `reddit`, I committed the needed CSS.
