Spaces are stripped between consecutive tags

[nickcernis]

This test currently fails:

$this->html_gives_markdown("<b>Bold</b> <i>Italic</i>", "**Test** *Italic*");

Output:

Expected :**Test** *Italic*
Actual   :**Bold***Italic*

Need a better way to preserve spaces that exist between consecutive span tags.

This issue seems to be caused by line 78:

$html = preg_replace('~>\s+<~', '><', $html); // Strip white space between tags to prevent creation of empty #text nodes

This is stripping out the space which originally appeared between the two tags.

I did a quick test, and removing this line seemed to resolve the issue. However, the lists aren't excluding those text nodes when determining their positions, so they go 1, 3, 5, etc. I'll need to somehow exclude those.
