Do not indent textarea contents

Addresses problem raised in #102

Let me know if there are any style / testing issues with this PR.

Thanks @mwanji, I had a look at this fix a long time ago, this is what I had locally: #114. My fix is a little broken, ideally we shouldn't render "empty space" for the each tag. Maybe you can improve it?

[mwanji]

@tipsy I integrated your changes from #114 piecemeal here, as it was easier for me to understand it that way. The main difference is that the extra space and level of indentation have been removed from the RenderFormattedText::testFormattedTags_each unit test expectation.

I also replaced ImmutableList::of with Arrays::asList, to be able to remove Google Guava from the dependencies.

Thanks, looks great!

This has been released in 1.3.0 now.

Cool, thanks.
