Use raw data (rather than entities parsed version); required for new line preservation

[jamesporter]

I was processing some content which had code samples. Unfortunately the newlines were lost in the entities process.

This is simplest way I could think of solving this (can pass in an optional rawData along with data to preserve the raw string (with newlines). If nothing is supplied will just use content.data as before.

Hi @jamesporter,

Just an heads up that I've merged #51 that reverts this PR but also removes white space stripping so you can just use/set content.data as usual from now on, and that whitespace stripping shouldn't occur.

Will release a new version with this soon.

Cheers!
