Fix Author names: escape special characters

When the author name contains an apostrophe " ' ", the client will show it as " \\ \\ \\ ' "
(mostly noted on TheVerge feed, Dante D'Orazio, check attached screenshot)

I fixed this by applying the StringUnescapeUtils.unescapeJava.
To avoid importing the whole apache-commons-lang, I imported the needed function to the utils package.
