Add a TextResponse to easily return plain text HTTP responses

[mnapoli]

Fixes #76

I did not add a charset as the HtmlResponse didn't have one. Maybe this is something to add? (see e.g. in symfony). I am very far from an expert in HTTP stuff, so I'm just bringing it up but I have no idea (and it should probably be done in a separate PR anyway).

text/plain, not text/html.

Thanks @akrabat I've updated the commit.

Yes, please. :)

Looks good; I'll wait for your feedback as to whether or not you want to add charset to this PR as well before merging, however.

[mnapoli]

Will do tomorrow! I'll add it on HtmlResponse too. UTF-8 by default?

Awesome!

UTF-8 by default?

Of course!

[mnapoli]

I've pushed a new commit setting UTF-8 for HTML and text responses (new commit as I think this is a separate change since it also applies to HtmlResponse).

From what I have read online (example: http://stackoverflow.com/a/19815111/245552) JSON is UTF-8 (mandatory) so there is no need for a charset.

Merged to develop for release with 1.2.0. Thanks, @mnapoli !
