Subject: [PATCH] fixes #2120 add new return value to 'pwg.categories.move'
 method API

Added a new return value for API method 'pwg.categories.move': updated_cats . This value returns an array of albums whose values have been modified after an album has been moved (for the moment, the data is the id and the number of photos in its sub-albums).
