Subject: - remove useless __construct() - renamed empty filter to Null filter
 - columns are now renamed recursively, fixing bug in not valid XML code when
 the columns still had a numeric name - added a new parameter in API for
 Referers module: expanded. If set to true, it will load the data recursively
 (eg. all keywords + the search engines for each keyword).
