Should Default to HTML5

[ma11hew28]

When I run jekyll serve, I get:
___________________________________________________________________________
| Maruku tells you:
+---------------------------------------------------------------------------
| Maruku cannot parse this block of HTML/XML:
| |
| Missing end tag for 'input' (got "html")
| Line: 4
| Position: 226
| Last 80 unconsumed characters:
+---------------------------------------------------------------------------

input doesn't need an end tag in HTML5.

Perhaps this is an issue with Jekyll, but whether it's Jekyll and/or Maruku that's lagging behind, HTML5 should be the default by now.

I'll see if there's some setting I can configure to validate HTML with HTML5 rules.

I see that a comment on Jekyll issue #1261 says to use Redcarpet instead of Maruku. I'll try that.

Resolving in favor of #56.
