Discard post confirmation closer to editor

Seems disjointed to have to confirm [Discard] post so far away.

I used bootbox to render those confirm modals.

Could easily remove that and change the "discard" button so that when clicked, it gets replaced with [No | Yes]

In addition I think it may be a bit confusing when receiving that message when you're discarding a post that you're editing

lol @psychobunny -- that as a half-hearted attempt at adding the post discard confirmation.

I just added a check to calculate the textarea's value length, but it should really be a flag that is toggled onchange

Fixed it up now, so it doesn't show up on edit (unless something changed)
