AWS::S3::Connection.prepare_path doesn't properly escape plus sign '+' in key

[tekwiz]

AWS::S3::Connection.prepare_path isn't properly escaping the plus sign in a key. This is because the plus sign is sometimes used to represent a space (at least according to the Ruby devs) i.e. the URI.escape() doesn't convert '+' to '%2B'...

Solution: Add a special gsub on line 11 i.e. URI.escape(path) to

URI.escape(path).gsub('+', '%2B')

I have anecdotal evidence that & and ' are also not escaped correctly, and therefore the line in connection.rb should actually be:

      URI.escape(path).gsub('&',CGI.escape('&')).gsub('+',CGI.escape('+')).gsub('\'', CGI.escape('\''))
