Pasting text that contains a newline inside a list throws an error

[YoranBrondsema]

To reproduce

1. Go to the demo (https://bustlelabs.github.io/mobiledoc-kit/demo/)
2. Add a list (either unordered or ordered)
3. Copy the two lines in the "RAW Paste Data" section in http://pastebin.com/CdrMjutM and paste into the list

You would expect it to create a new list item for each line of text but instead it throws an error Uncaught Error: Cannot insert non-list-item to list (is: markup-section).

I figured it's because parsePostFromText transforms the text into paragraphs, divided by the newlines. Then it makes sense that it fails.

A solution would be to turn the parser into a "context-dependent" parser, i.e. if the cursor is in a list, then parse this particular example as list items, else as paragraphs. Any thoughts on this @bantic @mixonic?

Alternatively, do a transform when inserting the items to the list section.

@YoranBrondsema Thanks for the detailed bug description...I'm looking into it this morning.
