Fixes line breaks in paragraphs

[martin-lysk]

This pr introduces a serailization that allows to serailize whitespaces comming from plate lossless into markdown.

Markdown whitespace handling is a beast - two \n represent a paragraph but following ones get collapsed.

Mardkown	Gets rendered as
Hello new paragraph	Hello new paragraph

empty paragraph	paragraph with one softbreak	paragraph with two softbreak
Hello new paragraph	Hello new paragraph	Hello new paragraph
Hello <br /> new paragraph	Hello <p><br /></p> new paragraph	Hello \ <br /> new paragraph
