#to_text should preserve whitespace between inline elements

[timherby]

@flavorjones I love the that #to_text preserves whitespace (as you added here #12), but it doesn't appear to preserve between inline elements as you say in this post (sparklemotion/nokogiri#636), only block elements. Would it be reasonable for it to preserve whitespace between inline elements? Am I missing an option to do this? If not, would you be open to a pull request to make this happen?

An example of what I was hoping for:

html_text = "example:<a href=\"http://url.com/index.html\">http://url.com/index.html</a><a href=\"http://url.com/index2.html\">http://url.com/index2.html</a>"
Loofah.fragment(html_text).to_text

Expected:
"example: http://url.com/index.html http://url.com/index2.html"

Actual:
"example:http://url.com/index.htmlhttp://url.com/index2.html"

Similarly,
tags are not being seen as block tags:

html_text = "example:<br><a href=\"http://url.com/index.html\">http://url.com/index.html</a><br><a href=\"http://url.com/index2.html\">http://url.com/index2.html</a>"
Loofah.fragment(html_text).to_text

Expected:
"example:\nhttp://url.com/index.html\nhttp://url.com/index2.html"

Actual:
"example:http://url.com/index.htmlhttp://url.com/index2.html"

I'd love to have this too.

I set the gem's version to github and found that it's supported! Also, note that you need to call the method to_text rather than text, I thought they were the same.

I'm open to a PR of some sort that generates output as you describe. Let me know if you'd like direction or advice?
