Fix Post#url escape

Post#url was escaped using CGI.escape.
When file name contains a space character, its url points to
non-existing URL.

For example, when we have a post named '2014-01-02-foo bar.md',
we expect its url to be '/2014/01/02/foo%20bar.html',
but it was actually '/2014/01/02/foo+bar.html'.

We now define Jekyll::URL.escape_path and Jekyll::URL.unescape_path,
and use them to escape and unescape Post#url
Fix Page#url escape

Post#url wasn't escaped at all.

For example, when we have a page named 'a#b.html',
we expect its url to be 'a%23b.html',
but it was actually 'a#b.html'.

We now use Jekyll::URL.escape_path and Jekyll::URL.unescape_path.
Move URL escape to Jekyll::URL

For the case when more than one category specified in the news item, make sure category names formatted nicely with comma delimiter like this: category1, category2. Instead of categor1category2.
