Easier Post Formatting with Markdown

It's true that there's a whole suite of BBCode available, both in the full composer window and potentially in your memory if you're really good at recalling tags and don't mind manually writing them out...

But come on. There are easier ways to prettify our posts.

Now, there's certainly a lot of things about Discord that I'm not a fan of, but one thing that is pretty cool is that it uses something akin to Markdown syntax. That means it allows you to add things like bold text, italicized text, struck-out text, and:

• Lists
• Of
• Items

but to add those things, you don't even have to:

1. Click
2. Any
3. Buttons

The brilliant thing about implementing this into the site backend is that you get all those new formatting features without really having to select or learn anything. Using asterisks for emphasis makes sense even in plain text (it turns to italic now), two asterisks around a word or phrase sets it off more (in Markdown it turns to bold), and using - or 1. for lists is also pretty straightforward.

I haven't put the new code in place for the quick reply composer yet - which will make this functionality even easier to understand and use - but that's coming, and for now you can already use the features I've listed above easily enough. It also works in the chat!

It should be noted that I don't think spoilers work yet as implemented in the MD code, but I'll try to add that feature soon enough. I think I'll add something that displays inline with the rest of the text, rather than having a whole separate spoiler block that shows up.
