Title: Extracting CategorySelect.class.php from CategorySelect extension

There are few extensions using helper methods from CategorySelect class. In each place when it's being used it's also wrapped with if statement. After short discussion we decided to extract this class:
* moved the class to /includes/wikia/helpers/ and renamed it to CategoryHelper,
* removed the line in setup file and add one more lines to DefaultSettings.php,
* unit tests were also moved and renamed,
* created CategorySelectHelper class in the CategorySelect and left there two helper methods which are connected only to the extension,
* added more PHPDoc and did small adjustments after linting.
