Enable task lists (from GFM)

[JoseTomasTocino]

GFM lets you create Task Lists using the following syntax:

- [ ] First item
- [x] Checked item

Which renders the following:

• First item
• Checked item

It would be great to have that feature in marked.

@JoseTomasTocino vote for this feature #129

You can easily setup the task feature with renderer.

[JoseTomasTocino]

I'd rather have it natively, as it's a native feature of gfm.

Duplicate of the previous #107 and #111 issues.

@JoseTomasTocino You must misunderstand, GitHub build gfm on sundown with its renderer feature, there is no such thing as built-in.

[OscarGodson]

@lepture, no, I see what he is saying. You can do it your way, but then you'd have to set it up, no? Especially with my project, I need it to be work natively or I'm most likely not going to support it.
