+ Resolves Issue #220.
+ Added escapeURI function to Markdown reader. This escapes
links in a way that makes sense for markdown. If they've
used URI escapes like %20 in their link, these will be preserved.
But if they've used a special character or space without escaping
it, it will be escaped. This should make sense in most cases.
+ Previously pandoc collapsed adjacent spaces and replaced these
sequences of spaces with + characters. That isn't correct for
a URI path (+ is to be used only in the query part). We've also
removed the space-collapsing behavior.
