URL parsing

To start, great plugin. Just as a note, I found that trailing slashes on URLs tend to not be parsed properly in the wpsl-gmap.js (i.e. http://www.test.com/ would be parsed as “http://www.test.com/”, closing the anchor tag before the text). I found that encapsulating the href value in single quotes fixed it (line 730).
