Support Task Lists in GFM

[Vdragon]

It seems that Task Lists still not rendered correctly.

Task lists unfortunately aren't supported in chjj/marked, which is the markdown rendering library this editor uses.

That said, I'm currently working on rearranging a whole load of code and potentially switching to markdown-it as the markdown parser, which doesn't have support for task lists out-of-the-box, but it has quite a nice plugin system so I'm sure it'll be possible to add.

One question: obviously task lists will render checkboxes into the final output - would you want the ability to be able to toggle them on and off and it change the markdown source, or would you be happy with them being readonly? (obviously readonly is quite a lot easier to implement)

Readonly would be fine for me.

I'll see what I can do then :)

Just FYI on this, after switching to markdown-it it looks like this would be very easy to do, but I don't like the available markdown-it-checkbox package (it doesn't give a nice way of applying a class to the enclosing <li>) so I'll have to see about putting something together myself. Shouldn't be too bad though.

I'd like to be able to choose if I were to have a check-box or simply a graphic for the output or the ticked checkbox from font awesome.

Read-only is good for me too, this would be a helpful addition.

It would be really great if this feature would be supported. This is the only reason I still use GitHub markdown API instead of this project.

I'd like to support this.
