Feature: #45725 - Added recursive option to folder based file collections

See forge#45725


Folder based file collections have now an option to fetch all files recursively for the given folder. The option is also available in the TypoScript Object FILES.


filecollection = FILES
filecollection {
        folders = 1:images/
        folders.recursive = 1

        renderObj = IMAGE
        renderObj {
                file.import.data = file:current:uid
